"An unassuming, always-busy taco stand in Mexico City's historic center that you spot by a huge vat of bubbling meats — a 'meat jacuzzi' filled with everything from ojo (cow eyeball) to tripa (tripe) — with locals clustered around the salsas. Tacos run about $1 each, and it's wise to order more than you think you'll need; meats are ladled from the big metal pot, chopped on a fat-stained cutting board, and served on corn tortillas. Favorites include suadero (moist, fall-apart, showered with cilantro and chopped onions — so good the writer went back for a second helping), longaniza (sausage), and cachete (beef cheeks)." - ByRachel Karten
