I wanted to eat here because it serves Puerto Rican cuisine and is the oldest restaurant around. It opened in 1848 and has been in the same location since that time.
The atmosphere is really nice, and it's not too loud. The service was good, and the interior was classy (colonial ambience). I ordered the octopus with garlic for an appetizer and a prawn dish for my main course. To be honest, the food wasn't THAT great--it was nothing to fuss about--but it was good. I had flan a la mode for dessert, which was really good.
My friends both had a rice soup dish. The portions there were fairly small--so it ended up being quite pricey. I would probably want to go there again to try other dishes.
