We stumbled upon this wonderful place in Puebla and felt Chowhounds deserved a heads up! Las Ranas (The Frogs) is a very casual place on Av. 2 Poniente between Av. 5 de Mayo and Calle 3 Norte. There are 2, but the best one is the big one, not the annex. It has incredible tacos al pastor con pan arabe (with a kind of pita instead of tortilla) and other grilled meat dishes. It is also incredibly cheap - for 4 large tacos al pastor arabe, a plate of grilled steak with queso fundido, a stack of tortillas, 2 beers and 2 waters, we paid 95 pesos. We went back again today for lunch because it was truly awesome. The place is always packed but service is great, friendly and very fast.
