Centro Historico is home to museums, the Zocalo plaza, and what we have to assume is the largest Mexican flag in the known universe. It’s also where you’ll find Taqueria Los Cocuyos making excellent tacos 24 hours a day. This tiny stall is basically just a cauldron full of different meats, a well-worn cutting board, and a salsa station, but that’s really all they need to deliver some of our favorite tacos in the city. Each one is made to order with whatever meat you want from the simmering pot chopped up, tossed onto a fresh corn tortilla, and topped with onion and cilantro. Everything here is excellent, but we like the longaniza and campechano (a mix of carne asada, longaniza, and chicharones) the most.
