Location: 114-118 Southampton Row, Holborn ·

Eight key facts, one pattern: Swiss Butter keeps it simple – limited menu, fixed hours, no fuss.

The implication: Swiss Butter’s entire model rests on stripping away everything except the meal itself.

How much is a meal at Swiss Butter?

Pricing at Swiss Butter is refreshingly simple: one price for steak platters, a similar range for chicken and salmon. Here’s what you’ll pay.

Steak platter prices

• Fillet steak and ribeye steak platters are £19.95 each, as posted by a recent visitor on Facebook (visitor review).
• A review on Foodepedia (restaurant review) estimates mains at about £19 each.

Chicken and salmon pricing

Exact prices for chicken breast and salmon fillet are not listed publicly, but Tripadvisor (user reviews) indicate all three mains sit in a similar £19–£20 bracket. A pint of beer adds £5, per Foodepedia (restaurant review).

Value for money

At under £20 for a steak platter in central London, Swiss Butter undercuts most competitors by a wide margin.

Is Swiss Butter walk-ins only or do you need to book?

Swiss Butter’s booking policy is one of its most talked‑about features. The answer is clear: no reservations are accepted.

Walk-in availability

The official Swiss Butter (official website) explicitly states that the restaurant operates on a walk‑in basis. The Instagram (official profile) bio lists hours but makes no mention of a booking system.

Reservation options

No online reservation portal exists on the site, and third‑party platforms like OpenTable don’t list Swiss Butter. For large parties, the restaurant has not indicated whether exceptions are made.

Peak times

Instagram posts frequently show queues, suggesting that evenings – especially weekends – fill quickly. Arriving early is the safest strategy.

The trade-off: you save the booking hassle but risk a wait. Plan accordingly – a 6 PM arrival is wise for dinner.

Why is Swiss Butter so popular in London?

The restaurant has generated a surprising amount of buzz for a three‑item menu. The reasons boil down to sauce, simplicity, and location.

Secret sauce appeal

The “secret Swiss Butter sauce” is the headline act. Swiss Butter (official website) promotes it as the defining flavour across all mains. Foodepedia (restaurant review) describes the concept as bringing “a bit of Beirut, Riyadh, and Dubai to Holborn.”

Limited menu strategy

By offering only three proteins, Swiss Butter avoids choice paralysis. The model relies on doing one thing well – and that thing is steak with sauce. Tripadvisor (user reviews) consistently praise the focused menu.

Location and value

Holborn is a busy central London hub, and Swiss Butter sits right on Southampton Row. The £19.95 steak price, confirmed by Facebook (visitor review), is a bargain for the area. Tripadvisor (user reviews) call it “incredible value.”

The pattern: Swiss Butter bet on scarcity – one sauce, three proteins, one UK location – and it paid off.

Is there a dress code at Swiss Butter?

No official dress code has been published, and the question seems to arise largely from online curiosity.

Casual dress code expectation

Swiss Butter (official website) does not mention any dress requirements. Photos on Tripadvisor (user reviews) show diners in jeans, T‑shirts, and casual footwear.

Source of dress code question

The question appears frequently in “People also ask” search results, suggesting that visitors want reassurance before arriving. In practice, any reasonable casual attire is fine.

The catch: the absence of a stated dress code means anything goes – but that also means no surprises if you show up in shorts.

What is on the Swiss Butter Holborn menu?

The menu is deliberately tiny. Here is the full breakdown, confirmed by multiple sources.

Mains: beef, chicken, salmon

• Beef fillet or ribeye steak
• Chicken breast
• Salmon fillet
• All three are smothered in the secret Swiss Butter sauce (Swiss Butter (official website))

The secret Swiss Butter sauce

The recipe is not publicly disclosed. Swiss Butter (official website) calls it “secret” and uses it as the unifying element across the menu.

Sides and drinks

Each main comes with a mesclun salad, a baguette, chili flakes, and a choice of fries or baked potato (Swiss Butter (official website)). For dessert, Tripadvisor (user reviews) list molten chocolate fondant and pain perdu. A pint of beer costs £5 (Foodepedia (restaurant review)).

What this means: the menu is deliberately tiny – the focus is execution, not choice.

For anyone looking for a no‑fuss steak dinner in central London, Swiss Butter offers a formula that’s hard to beat: a tight menu, a distinctive sauce, and a price that undercuts most of its Holborn neighbours. The walk‑in policy keeps things honest – no reservation, no dress code, just show up and eat. For the budget‑conscious diner, the choice is clear: get there early, order the fillet, and save your £5 for a pint.
