I am new to the Nassau county area by way of Chicago and have not had really any good dining experiences thus far. I don't know many people and the places I have been told to try have not been that good. Are there any authentic Greek/Spanish food places? I notice a lot ( A LOT) of chains and Italian restaurants which seem to serve the same things everywhere. So I guess my question is simple: what are the absolute best places to eat on Long Island? Cheap, expensive, doesn't matter, I just want good!!!
