With up to one in ten American restaurants selling Mexican food, no-one is better at sniffing out this cuisine than our trans-Atlantic cousins. So to find, therefore, important-looking US diplomats squeezing inside Urban Burritos is an endorsement in itself. Their faith is rewarded by high standard tacos and burritos heaped with fresh fillings. Whilst some say the habanero salsa lacks the dynamite touch, that hasn’t stopped this little chunk of Mexico from gaining a staunch following.
