Swiss Butter Holborn Menu: Prices, Walk-Ins & Guide

Swiss Butter Holborn defies conventional restaurant logic — no reservations, one signature sauce, queues until midnight — yet ranks among London’s top 10.6% of rated establishments. This walk-in steakhouse draws repeat customers for a menu of just three mains, all smothered in a 33-ingredient secret sauce created by a Lebanese chef in 2015.

Location: Holborn, London · Main Dishes: Beef filet or ribeye, chicken breast, salmon filet · Signature Sauce: Swiss Butter sauce · Reservations: Walk-ins only · Cuisine Focus: Casual steakhouse

The table below consolidates key operational and descriptive details for Swiss Butter Holborn, drawn from verified sources including TripAdvisor, the official website, and published restaurant reviews.

How much is a meal at Swiss Butter?

At Swiss Butter, the pricing structure follows the same minimalism as the menu. Every main dish — whether you choose beef filet, ribeye, chicken breast, or salmon filet — costs a flat £19.95 per item. That single price covers the protein, the signature Swiss Butter sauce smothered over it, and the full spread of accompaniments: mesclun salad, white or brown baguette, chili flakes, and either fries or a baked potato.

Steak prices

The beef options — filet or ribeye — sit at the core of the offering and attract the majority of visitors who make the pilgrimage to Holborn. At £19.95, the price positions Swiss Butter below many central London steakhouses, yet reviewers consistently note that the signature sauce elevates the experience beyond what the straightforward steak quality alone would suggest. The Infatuation’s review captures this dynamic: “You’ll find better steak in London, but you won’t find the Swiss Butter sauce anywhere else.”

Chicken and salmon costs

Chicken breast and salmon filet are not afterthoughts here — they receive the same Swiss Butter sauce treatment and come with identical accompaniments at the same £19.95 price point. For visitors who don’t eat beef, this parity matters. The salmon in particular draws positive mentions in reviews for its quality relative to price, though the beef options dominate the conversation.

Full meal estimates

For a complete meal including a starter or drink, most visitors report spending in the £25-30 range. Desserts add to this: the molten chocolate dessert costs £10, while pain perdu appears on the official menu as a dessert alternative. Students frequent the venue for what The Infatuation describes as “£20 steak and chips meals,” suggesting many visitors stick to the basics. Alcohol is served, and credit cards are accepted — the restaurant is fully equipped for a conventional dining experience despite its casual shack aesthetic.

Why is Swiss Butter London so popular?

Swiss Butter London has carved out a distinctive position in the capital’s restaurant scene through a combination of deliberate constraints and a single unforgettable selling point. The operation is simple: three mains, one sauce, no reservations, and an open kitchen housed in what reviewers describe as a tin “shack” in the centre of the dining room.

Secret Swiss Butter sauce appeal

The sauce is the engine behind everything. Created in 2015 by a Lebanese chef using a reportedly 33-ingredient secret recipe, the Swiss Butter sauce has become the reason people queue. Foodepedia describes it as creamy, peppery, and citrussy — a combination that The Infatuation recommends soaking into sliced baguette or using to drench skinny fries until they turn soft. That specificity in the recommendation suggests the sauce works as both a condiment and a flavor system applied across the entire plate.

Limited mains driving demand

The three-mains-only menu removes decision paralysis and creates scarcity appeal. When every option on the menu costs the same and receives the same signature treatment, visitors who might otherwise agonize over a steak cut simply choose their protein and move on. TripAdvisor reviews frequently mention the “simple” or “limited” menu, but consistently frame this as a positive — the simplicity is the point. Management describes the venue as “your friendly neighborhood steakhouse. A place for everyone to come in and enjoy a good meal,” deliberately positioning it as unpretentious and accessible.

London launch buzz

The restaurant currently holds a 4.1 out of 5 rating on TripAdvisor with 248 reviews, ranking #2157 out of 20,380 London restaurants — placing it in the top 10.6% of establishments in the city. That ranking reflects strong visitor satisfaction despite (or because of) the walk-in-only model, the open kitchen, and the casual Shack atmosphere. The queues that form during peak hours, sometimes extending until closing at midnight, suggest the buzz has translated into sustained demand rather than a flash-in-the-pan opening.

Can you book a table at Swiss Butter London?

Swiss Butter London operates strictly on a walk-in basis — no reservations are accepted, and there are no plans to change this policy. For visitors accustomed to planning meals in advance, this is the single most disruptive aspect of the Swiss Butter experience.

Walk-ins only policy

The walk-in-only model is a deliberate operational choice rather than an oversight. Management has leaned into it as part of the restaurant’s identity — “your friendly neighborhood steakhouse” suggests an accessible, first-come-first-served ethos that no amount of advance booking would support. TripAdvisor reviews confirm this explicitly: visitors who arrived expecting to book a table were turned away, and those who understood the model from the start arrived ready to wait.

Queue experiences

Queues at Swiss Butter form during peak dining hours and can extend until closing time at midnight, according to multiple TripAdvisor reviewers. The open, airy layout — described by Foodepedia as “airy and open” with the kitchen in a tin shack at the centre — means there is no physical barrier between the cooking operation and the dining room, and the limited menu keeps table turnover relatively brisk. However, the popularity of the venue means that during busy periods, waits can be substantial. Visitors who prioritize predictability in their dining plans should factor this in.

UK restaurant details

Swiss Butter Holborn is currently the only UK branch of the restaurant. Management has expressed plans to open “a hundred more outlets in coming years,” according to Foodepedia, though no timeline or specific locations have been confirmed. Until expansion materializes, the only way to experience the Swiss Butter concept in the UK is the Southampton Row location in Holborn, which is wheelchair accessible and open for both lunch and dinner service.

What is the main dish at Swiss Butter?

The main dish question has a straightforward answer at Swiss Butter, but the context makes it more interesting than the menu suggests. Every main comes from the same kitchen, receives the same sauce, and arrives with the same accompaniments — the only variable is the protein.

Beef options

Beef dominates the conversation at Swiss Butter, with two cuts available: filet and ribeye. Both are priced at the flat £19.95 rate and both are served smothered in the signature Swiss Butter sauce. TripAdvisor reviewers and The Infatuation both note that the beef quality alone would not necessarily set Swiss Butter apart from other London steakhouses — it is the sauce that elevates the experience. One TripAdvisor reviewer describes it as “hands down the best steak I’ve had in London,” while acknowledging that the sauce is the differentiating factor.

Chicken breast

Chicken breast serves as the non-beef default and receives the same Swiss Butter sauce treatment as the beef options. Reviewers who mention the chicken generally describe it positively, though the beef options receive more attention in reviews. The price parity (£19.95) makes chicken a legitimate choice rather than a consolation option, and the sauce appears to work equally well with poultry.

Salmon filet

Salmon filet is the third main and the most distinct protein from the core beef offering. Like chicken and beef, salmon arrives smothered in Swiss Butter sauce and comes with the full accompaniment spread. Visitors who don’t eat red meat but want the signature sauce experience can participate fully without compromise — every main receives the same treatment.

How much is steak at Swiss Butter?

Steak at Swiss Butter costs exactly the same as every other main: £19.95 for either the beef filet or ribeye. There is no price distinction between the two cuts, no premium for ribeye over filet, and no upgrade fee for choosing beef over chicken or salmon.

Ribeye pricing

The ribeye at £19.95 positions Swiss Butter below many central London steakhouses where ribeye typically commands a premium over filet. For visitors who understand what they are getting — a decent cut with the transformative Swiss Butter sauce applied — the value proposition is strong. For visitors expecting premium dry-aged beef from a high-end steakhouse, the price reflects the casual positioning.

Filet costs

Beef filet at £19.95 represents the leanest cut on the menu and attracts visitors who prefer a milder beef flavor without the marbling of ribeye. At the same price point, the choice between filet and ribeye comes down to personal preference rather than budget, which removes one common source of decision friction in steakhouse dining.

Value comparison

At £19.95 for any main — protein, sauce, and accompaniments included — Swiss Butter undercuts most comparable central London steakhouses while delivering a unique experience that those competitors cannot replicate. The sauce is the variable that makes the comparison complex: at a traditional steakhouse, you might get better beef, but you won’t get Swiss Butter sauce. The Infatuation’s assessment captures this trade-off: better steak exists in London, but the sauce does not.

What people are saying

Hands down the best steak I’ve had in London. The butter is so so so delicious, words don’t really do justice. The staff is friendly & the service is quick!

— TripAdvisor reviewer

A creamy, peppery, citrussy sauce that’s best soaked into sliced baguette or used to drench skinny fries until they’re soft.

— The Infatuation restaurant critic

Your friendly neighborhood steakhouse. A place for everyone to come in and enjoy a good meal.

— Swiss Butter management

The visitor reviews converge on a consistent theme: the Swiss Butter sauce is exceptional, the service is brisk, and the overall experience punches above what the straightforward menu and casual Shack atmosphere would suggest. The Infatuation’s assessment is notably measured — acknowledging that better steak exists in London while affirming that Swiss Butter’s sauce is irreplaceable. That trade-off — slightly sub-premium beef, transcendent sauce — defines the restaurant’s niche.

Frequently asked questions

For visitors who do not want to wait in a queue, the decision is clear: arrive before 6 PM on weeknights or during off-peak hours, or choose a different restaurant with a reservation system. Swiss Butter’s walk-in-only model is not a technical constraint — it is a deliberate choice that defines the experience and the customer base it attracts. For visitors who want to experience the 33-ingredient sauce without the gamble, planning around the queue is the only reliable strategy.
