Recommend a good Lounge

My DH is turning 30 and I want to have a nice party for him. I am looking for a lounge type of place that I can have about 50 people. I know the really nice ones are in the city, but I don't want to go out there. Please recommend any places in Nassau.

There is a nice Lounge in Great Neck
I am drawing a blank on the name.

Also there is a nice place in Rosyln that you can rent the upstairs
