Just returned from a few days in South Beach and was delighted with all the relatively inexpensive, tasty ethnic food there was to be had (which I found based on recommendations here). I liked the lunch at Puerto Sagua on Collins and returned next day for Cuban coffee and guava & cheese pastry. I liked my dinner at the Haitian restaurant Tin Tin. I had a delicious potato appetizer at the Peruvian restaurant El Chalan on the Beach, so filling I had no room for a main dish! (but I did have some good natural juice, mango I think). I had wonderful key lime pie at Joe's Stone Crab; the so-called "takeout" part has tables & counter and was just fine (other part too pricey). Wish I'd had room for a crab cake sandwich; will have to return some day for one. Thanks to everyone at Chowhounds for your great recommendations.
