Despite its newfound popularity on TikTok, this cheerful spot remains a good, casual option for Mexican street food. A true family-run business - both the parents and their grown children are often featured in the videos busily running the shop - Ollin serves everything from tacos to their thick, Puebla-style cemita milanesa. If it’s your first time, definitely try the original birria tacos, stuffed with rich goat stew, heated on the griddle until the cheese is gooey, and served with a side of consommé.
