There are a few taco places at Grand Central Market, but Tacos Tumbras a Tomas is the oldest of them all. There’s often a line, and it’s for their carnitas. There’s a wide range of meat choices, including birria (goat) and carne asada, but if you don’t opt for the carnitas you’ve made a mistake. You’ll only need a single order—just ask for more tortillas to go with your one taco and you’ll have enough protein for at least three. If you top with green salsa and order a Mexican Coke, you’re doing Grand Central Market right.
