This cozy subterranean space feels like an undiscovered hideaway, but the secret is officially out. Though waits can be long, the warm staff keeps things moving while guiding guests through a frequently changing menu of Mexican-inspired shared plates. Familiar favorites and seasonal specials make for a festive spread, where creative ideas remain rooted in comforting flavors. The signature 1000-layer potato, crisped until golden and topped with creme fraiche, tobiko and chipotle cream, is an indulgent crowd-pleaser, while the generously portioned Plato Placero invites diners to build bites with tender beef brisket, roasted plantains, Oaxaca cheese, fresh salsas and crisp lettuce wraps. Finish with the chocolate-chile mousse, whose spiced goat cheese center and toasted marshmallow sauce make for a satisfying finale.
