MA/NA Mayfair: 14-seat counter, ingredient-first kaiseki, no reservations

May 17. MA/NA Mayfair opened this week in central London at 20 Berkeley Street. Fourteen seats at a counter. No reservations. Ingredient-led kaiseki that changes daily based on what's available that morning.

The room is minimal. Timber counter, low lighting, no tablecloths. Designed by the in-house team at Thesleff Group, the hospitality group behind ROKA and Zuma. The kitchen is visible from every seat. Chefs work in silence. Plates arrive without announcement.

The menu is whatever the head chef sources that day. Spring peas one night, Cornish mackerel the next. No set tasting menu, no wine pairing package. You eat what's ready. The format recalls Kyoto kaiseki more than London omakase, where the structure is less theater and more rhythm. Seven to nine courses. Each one smaller than the last place you'd call this kind of cooking "fine dining."

Pricing sits at £95 per person for the full sequence. Walk-ins only, first-come seating from 6 PM. The counter fills by 6:20 most nights, according to early reports from diners who posted reservation attempts and were turned away. No phone bookings. The door policy is the same as the menu policy: what's available is what you get.

Thesleff Group has been building this format for three years. MA/NA is the fourth concept under the group's umbrella, but the first built around a no-reservations counter model in this price tier. The bet is that London's Mayfair crowd will show up without a table guarantee if the food is specific enough. So far, the line suggests they will.

The space holds twenty-eight total, but only the fourteen counter seats get the full kaiseki sequence. The remaining tables are for à la carte, a shorter menu that borrows from the same daily sourcing but doesn't follow the kaiseki structure. The counter is the real room. The rest is overflow.
