I'm back in town from Chicago where I lived for four years and was treated to some excellent South/Central American cuisine. Am new hound here, looking for some recommendations. Trying to surprise a friend just back from Paraguay with an authentic place.
If you don't mind a somewhat dicey looking but perfectly safe neighborhood in north philly, there's Tierra Columbiana which is half Cuban, half Columbian. The food is great and reasonably priced, they often have live music, and always have salsa dancing on the weekends.
The same owners run a place called Mixto in Center City. They are sort of pan-latin. I've never been, but heard the food is good, but maybe not quite as authentic.
The ceviche samplers at Pasion are good as is the roast suckling pig, the rib eye, and the skirt steak. The seafood entrees there can be hit-or-miss. They do have a relatively new pastry chef who does great work... Try to sit at the Ceviche Bar at the back that overlooks the kitchen if you go.
