Restaurant in London, United Kingdom
Mayfair access without the usual booking battle.
Isabel on Albemarle Street is one of Mayfair's more accessible bookings, with a social atmosphere that makes it a solid pick for weekend brunch or a relaxed lunch. It sits above the casual all-day café tier without the formality of a full tasting-menu room. Book here for daytime; save the heavier-hitting Mayfair rooms for dinner.
Isabel is easier to book than most of Mayfair's high-end restaurants, and for weekend brunch in particular, that accessibility is part of the appeal. If you picture Isabel as a quiet neighbourhood spot, reset that expectation: this is a polished Mayfair address on Albemarle Street, positioned squarely in the same postcode as some of London's most competitive fine-dining rooms. The crowd it draws is cosmopolitan and the energy reflects that.
The atmosphere at Isabel skews warm rather than hushed. Expect a room that feels social — conversation-level noise, well-spaced tables, and the kind of ambient energy that makes it a credible choice for a long weekend lunch rather than a business dinner requiring library-quiet focus. For solo diners and pairs, this tone works well; for groups wanting a private-feeling occasion, it may feel a little open.
The brunch and weekend service is where Isabel builds its reputation most clearly. The format suits food-focused visitors who want something more considered than a hotel breakfast but less ceremonial than a full tasting-menu commitment. In a city where weekend brunch has become a competitive category, Isabel holds its position in the upper-middle tier: more composed than the casual all-day spots, but without the prix-fixe formality of a Michelin-calibre room.
Mayfair's dining scene has shifted recently, with several addresses repositioning around all-day formats and more accessible price points. Isabel fits that direction, offering a brunch experience that functions as a genuine meal rather than a holding pattern before dinner. If you are visiting London specifically for the restaurant scene, pairing Isabel with a heavier-hitting dinner reservation at somewhere like CORE by Clare Smyth or The Ledbury makes sense — Isabel for the daytime, the bigger rooms for the evening.

Key differences to consider before you reserve.
Isabel's kitchen is in Mayfair, where accommodating dietary needs is standard practice at this level of restaurant. Contact the team directly ahead of your visit to flag requirements — walk-in requests for complex restrictions are harder to fulfil than advance notice. The social, all-day format of the room suggests a menu broad enough to work around most common restrictions, but confirm specifics when booking.
Bar seating at Isabel is a practical option if you want a lighter visit or haven't booked a table. It suits solo diners and pairs well with the room's social atmosphere. If you're after a full sit-down dinner, reserve a table rather than banking on bar availability, especially on weekends when the room fills.
Yes, more so than most Mayfair restaurants at this tier. The room skews social rather than hushed, so solo diners don't feel conspicuous. Bar seating, if available, is the most comfortable solo position. For a solo special occasion dinner, a table reservation gives you more room to settle in.
Isabel works well for occasions where you want the Mayfair setting without the formality of somewhere like CORE by Clare Smyth or The Ledbury. The warm, social atmosphere suits milestone birthdays or celebratory lunches better than it does proposal-level intimacy. If hushed and ceremonial is what you need, look elsewhere on the street.
For a step up in formality and culinary ambition, CORE by Clare Smyth or The Ledbury are the natural comparisons in London. Sketch's Lecture Room and Library covers similar Mayfair ground with more theatrical presentation. If you want Mayfair brunch with a similarly social atmosphere but stronger name recognition, those are the benchmarks worth checking availability on before committing to Isabel.
For weekend brunch, book at least one to two weeks out — it's more accessible than most Mayfair restaurants at this level, but that accessibility is well known and tables move. Weekday lunch and dinner are easier. Isabel sits at 26 Albemarle Street W1S 4HY, so same-week walk-in attempts are more viable on quieter weekday slots than on Saturday mornings.
