Fig. A · The Classic, exploded view

Take it
apart.

Nine layers. Every one of them earns its place. Keep scrolling and we'll show you why.

Fig. 01

Freshly baked

Sesame brioche, out of the oven at five every morning. Toasted face-down so the sauce can't soak through.

Fig. 02

House sauce

Mayo, mustard, pickle brine, smoked paprika. The ratio stays in the kitchen.

Fig. 03

Cold crunch

Iceberg, straight from the fridge. It's there for crunch and nothing else.

Fig. 04

Thick-cut tomato

Beefsteak, a finger thick, salted thirty seconds before it goes on.

Fig. 05

Raw red onion

Shaved thin. A bit of bite to cut through the fat.

Fig. 06

Real cheese

Aged cheddar, laid on for the last forty seconds so it slumps down the sides.

Fig. 07

Premium beef

180 g of chuck and brisket. Smashed once, seared hard, salt and pepper only.

Fig. 08

The foundation

Buttered and griddled. It holds the whole thing up, right to the last bite.

Fig. B · Reassembly

Order is
the recipe.

Sauce under the patty, cheese on top of it, lettuce up against the crown. Change the order and you've made a different burger.

The art of a perfect bite.

Nº 003 · What goes in

Short list.
Long hours.

There's no secret ingredient. There are a few ordinary ones, done properly and on time, every day. Here's what that means in numbers.

180g
Of beef, weighed
Chuck for flavour, brisket for fat. Ground every morning and pressed by hand. Every patty goes on the scale.
05:00
Buns in the oven
Our brioche is proved overnight and baked before sunrise. What isn't sold by close becomes the staff's breakfast.
40s
Of melt
Cheese goes on for the last forty seconds under a dome. Long enough to slump down the sides, not so long that it splits.
0
Freezers for meat
We don't own one. If the beef doesn't arrive, the smash burgers come off the board for the day.

Nº 006 · Our story

It started
as a theory.

The hypothesis: a burger is only as good as the order you build it in. Fifty-two notebook entries later, we opened a restaurant to test it in public.

Entry 01
A question at 2 a.m.
Why does the third bite of a good burger always beat the first? We wrote it on a napkin. The napkin is framed by the till.
Entry 14
Forty-one buns later
Brioche held up. Potato squashed beautifully. Sesame looked the part. We kept all three and stopped arguing.
Entry 37
The order matters
Sauce on the heel, cheese on the hot patty, lettuce against the crown. Swap any two and it's worse. We tested that too.
Entry 52
Doors open
One grill, one plate for veg, thirty-four seats. The notebook is still on the pass. Ask to see it.

Nº 007 · The restaurant

Pull up
a stool.

Thirty-four seats around one very hot grill. Tap the plan to look around.

The grill

A flat-top hot enough to smash on. Sit at the bar and you're two metres from it.
