I went to a great restaurant on Broadway and 137th recently, called Cafe Largo. The food was mostly Latin (empanadas, arroz con camarones, grilled skirt steak) and very tasty. It's in a brownstone that the owner renovated himself -- tin ceilings, brick walls, etc. Saturday nights they have live music. All in all a very pleasant experience. I'm looking forward to going back.
I'd love to hear what others think about it.
