A lot of late-night decisions are questionable, but deciding to grab tacos at Atotonilco isn't one of them. It's a cash-only counter-service taqueria that’s open relatively late: 10pm during the week and 2am or 3am on the weekend. Most tacos here are good—the spicy and tender al pastor is well seasoned and crispy, and the carne asada and Atotonilco specialty (steak topped with crema, tomato, and onion slices) are so flavorful you don’t need salsa. That said, the salsa is great, and provides a refreshing contrast against all the meat. You can get your tacos to-go, or sit in a large, high-ceilinged dining room that’s perfect for groups.
