I have a friend visiting NY for one night from South America, and he wants to go out to have some Asian food. What are your favorite restaurants in the Slope/Cobble Hill/Fort Green area? My initial ideas are Long Tang (more because of the ambience, really), Osaka or Nana, but suggestions of places that are good and not too expensive would be great. Could be Japanese, Thai, Chinese, fusion etc. I just want a good place to take and out of towner who is here for such brief time- something that is an experience.
