Grill 23 Authentic Mexican

Birria Tacos lead the order at Grill 23, and the rest of the menu turns on it. Crunchy corn tortillas, onion, cilantro, lime, salsa verde, Mexican hot sauce, and a cup of birria caldo for dipping — the plate tells a first-time table what kind of Mexican counter they have walked into. The downtown London restaurant, family-owned and operating from Fullarton Street since 2022, treats the taco list as the centre of gravity and lets bowls, samplers, quesadillas, and a Family Combo orbit it.

The taco board reads as a tour through specific sauces rather than a single template repeated across proteins. Al Pastor, Carne Asada, Chorizo, and Guadalajara-style barbacoa sit alongside Birria, with a Grilled Shrimp version that brings garlic butter, chipotle mayo, and jalapeño-avocado sauce into the rotation, and a Black Bean-Quinoa Vegan option that keeps the meatless lane on the same board rather than parked in a footnote. The Birria-coa Sampler pairs two birrias with two barbacoas in a gluten-free build for guests who want both lanes in one order. Beyond the tacos, Build your Bowl turns the same proteins and toppings into a base-driven meal on rice, quinoa, or spring mix; Queso Birria and the MONSTERdilla cover the quesadilla side; Esquites and Mexican Guacamole sit on the shareable end; and the Family Combo bundles eight tacos, six quesadillas, chips, salsa, and sour cream into one order built for four. Dessert is a real beat rather than an afterthought — Tres Leches Cake, listed as gluten-free, in Dulce de Leche or Nutella.
