NWR: Location for Christening celebration

We're chistening our little boy in October and now need to find a new location for the gathering afterward. We had a location picked but that has since fallen through.

Can anyone recommend an intimate restaurant with good food and a room/separate party area for about 20-30 people? We would like to keep it in Nassau, preferably close to the Lynbrook, RVC Center area. But if the place is worth it, we will travel.

I appreciate any help you can provide ladies. FH and I just learned we would have to change our location this weekend and we've been scrambling ever since.

I had my engagement party and other family parties at Cafe Testarossa in Syosset.

We had an entire section to ourselves and my in-laws who paid said it was very reasonable.
