The 8 Best Mexican Restaurants in London 2026

London has exactly one Michelin-starred Mexican restaurant, and it refuses to import a single lime. Santiago Lastra builds KOL's acidity from sea buckthorn and fermented gooseberries instead, which tells you most of what you need to know about how far the city's Mexican cooking has travelled since the fajita-platter years. Below the starred tier sits a working ecosystem: a trompo turning in Borough Market, a Sonoran flour-tortilla counter in Stoke Newington, a tenth-floor party room above King's Cross. These are the eight rooms worth your evening in 2026, ranked.

How London learned to take Mexican food seriously

The shift has a date. KOL opened on Seymour Street in October 2020, took a Michelin star within fifteen months, and kept it through the 2026 guide, the only Mexican kitchen in the UK that can say so. What changed around it was supply and conviction: heritage corn nixtamalised in-house at half a dozen kitchens across town, mezcal lists that out-page the wine, and chefs from Mexico City, Puebla and Hermosillo cooking their own regions rather than a tourist's composite. The result is a city where the question is no longer whether to book Mexican, but which Mexico you want: Edomae-grade tasting-menu ambition in Marylebone, al pastor carved off the spit in Southwark, or beef-and-cheese caramelos from the Sonoran north. The London dining guide covers the wider field; this list is the Mexican chapter.

The eight, ranked

1. KOL — Marylebone

Santiago Lastra's room at 9 Seymour Street is the argument that Mexican technique and British produce belong in the same sentence. The langoustine taco, sweet Scottish shellfish on blue-corn masa with smoked chilli, has been the signature since opening night, and the kitchen's no-import rule (no limes, no avocados flown in) reads as discipline rather than gimmick once the plates land. One Michelin star, held since 2022, and the hardest Mexican table in Britain. Book a month out, and read the full KOL verdict before you choose between counter and dining room. Skip it if you want margaritas and chips; this is a tasting-menu room with mezcal pairings, not a cantina.

2. Fonda — Mayfair

Lastra's second act on Heddon Street, opened in 2023, runs à la carte where KOL runs the set menu, and lands around £100 a head with drinks. It is in the Michelin Guide, the cooking is home-style Mexican executed by a starred chef's team, and his cheesecake has already built its own following. The room is looser and the booking easier than the mothership, which makes it the smarter first date of the two. Pair the visit with the first-date playbook if the stakes are high.

3. El Pastor — Borough Market

The Hart brothers' taqueria at 7a Stoney Street has run its trompo since 2016, and the taco al pastor, pork shaved off the spit onto fresh masa with pineapple, remains the single best £5 bite in Southwark. No reservations for small groups, a queue that moves, and an agave list that rewards staying past the food. El Pastor's full review covers the sister sites; start at the original. Not for a quiet conversation: the railway arches keep the volume up.

4. Cavita — Marylebone

Adriana Cavita cooked at Pujol in Mexico City before opening her own room at 56 Wigmore Street in May 2022, and Cavita is the closest London gets to that capital's contemporary cooking. Wood-fired dishes, masa ground in-house, mezcal flights from small producers, and a chef who walks the dining room most nights. Mains sit in the £20s and £30s, so it is the realistic repeat-visit option in this tier. The Michelin Guide listed it within a year of opening.

5. Tacos Padre — Borough Market

Nicholas Fitzgerald cooked through Mexico City, Portugal and Berlin pop-ups before settling his counter into Borough Market Kitchen, and the suadero taco that resulted is the trade's own favourite taco in London. This is a market stall with a chef's CV, which is exactly the ratio you want: £15 eats like £50. Lunch only on most market days; check before crossing town. Not a date venue unless your date enjoys eating standing up in a Victorian market hall, which, to be fair, the right one does.

6. Decimo — King's Cross

Peter Sanchez-Iglesias runs the tenth floor of The Standard at 10 Argyle Street as a Spanish-Mexican party: wood-fired langoustines, carabinero rice, mezcal aguas frescas, and a DJ after nine. The cooking is better than the volume suggests, and the St Pancras clock-tower view is the best backdrop in the group. Book it for a birthday table of six, not a tête-à-tête. Decimo's full review explains which tables to request and which sittings stay civilised.

7. Santo Remedio — London Bridge

Edson and Natalie Diaz-Fuentes import their chillies and chocolate direct from Mexican producers and have grown from a 2016 pop-up into three sites across London Bridge, Shoreditch and Marylebone. The mole poblano, dark and properly bitter at the edges, is the dish to judge them by, and the upstairs tequila room at London Bridge is one of the city's friendlier private-dining secrets. Mid-priced, family-run, reliable: the Mexican restaurant to bring parents to.

8. Sonora Taquería — Stoke Newington

London's only Sonoran kitchen, at 208 Stoke Newington High Street, works in flour tortillas rather than corn, northern-style, and the caramelo, a grilled-beef taco welded together with a crisped cheese skirt, is worth the Overground ride on its own. Carne asada cooked over fire, tacos de cabeza for the committed, prices that stay in single digits. It is a neighbourhood operation with a regional thesis, and the thesis wins.

Where not to spend the evening

Skip the high-street chains for anything beyond a pre-train burrito; Wahaca feeds you adequately and quickly, but nothing on its laminated menu belongs in the same conversation as a trompo or a nixtamal tank. Be honest with yourself about Decimo too: it is the right room for a party and the wrong one for a first date you actually care about, because the DJ wins after 21:00. And if a menu anywhere in town offers fajitas, sizzling, with three flags of sour cream, guacamole and salsa, you are in a Tex-Mex museum piece, not a Mexican restaurant. The real thing is now too easy to find in London to settle.

Booking notes

KOL releases tables roughly a month ahead and Friday and Saturday go within the day; midweek counter seats linger longer and are the better experience anyway. Fonda and Cavita hold tables on the standard platforms with a few days' notice except around Christmas. El Pastor and Tacos Padre are effectively walk-in, which makes them the rescue plan when the starred rooms are full. Decimo needs two weeks for a weekend window table. If you strike out across the board, the wider strategy in the long-lead booking guide applies here in miniature: set the calendar alert for the drop, take the early sitting, and let the room fill in around you.
