Recommend a restaurant for a rehearsal dinner!

We would like to have our rehearsal dinner in the Northport--->Hungtington area. There will be people coming from Italy and Venzuela. We have a tough crowd to please. We dont want to choose a place that gives a pound of pasta nor do we want to choose a place that serves americanized fajitas. We had an issue with Jonathans a few years ago, so we won't go there again.

Any suggestions?
