Put in half an hour on the steep stairs and you'll be rewarded with exciting Mexican street food and jolly, slick charm. Waiters ferry zesty offerings around the buzzy, club-like dining room. Crisp tostadita rounds may come topped with a bright mixture of crabmeat, avocado, cucumber, tamarind mayo and habanero chilli, while soft tortillas enfold plump marinated prawns and chilli placated by a creamy chipotle almond salsa. For something richer, try confit chicken maryland in a bittersweet mole sauce of chocolate, spices and nuts, with a lime and salt-crusted Mexican beer for contrast.
