Lunch for 12 around Rye/Port Chester/White Plains
Many chowhounders on this board are not a fan of Zanaro's in City Center in WP, but I like it every now and then, and it would fit the bill here. You can ask for the "vault room", or a private area upstairs.
I have seen larger parties at Sunset Grille on Gedney in WP use the back room for exclusive parties.
I have had large lunches at PF Chang's at The Westchester, they pull the tables together, but it's a little loud.
PapaRazzi on Broadway in WP has sort of a side room. Laguna on E. Post Road in WP has large tables for large parties.
I think Water Moon on Purchase St. in Rye could put tables together for you, I have seen large groups there.
City Limits on Central Ave. may also be able to accomodate you.
I guess I should have updated. . .
We ended up at Rye Grill and Bar. I know, it's leaning towards the not so moderate price list. It has been a favorite of the company for some time and it is quite close to our office. Rather than take any chances on something new, we went to a place we knew. We had a really nice meal there and they took a reservation.
Part of the group had gone to PapaRazzi the night before and enjoyed their meal there. I am not a particular fan of Mary Ann's (they have the room but have always found the food to be mediocre). Eclisse had been my first choice before I found out they were closed. We had a nice company dinner there in February.
