My brother is getting married at the VIP and we are staying at the Crowne Plaza - they are having their Graziella's Restaurant on South Broadway in White Plains - (914) 761-5721 - it's Italian and they love it there - hope that helps!
Now you're talking my language, I live in White Plains! Graziella's is a great suggestion, my friends own it and we have tons of parties there. If you don't want Italian, there's a Cheescake Factory right across from the hotel as well as a PF Changs in the mall. If you're looking for something more laid back, you can go up to Mamaroneck Avenue and there are tons of bars, some with private rooms. The owners of Graziella's also just opened another restaurant that has asian influence, but it's pricey. If you have any questions, just ask. I can finally be more helpful now that you're in my territory!
