My Mom may come to visit me for Thanksgiving this year and instead of my cooking, she wants to go to a restaurant. Would appreciate any and all Chowhound suggestions in NYC. One caveat, not looking for out-n-out ethnic fare (i.e. Indian or Chinese), but open to Southwestern, etc. Already looked into Blue Hill, which was mentioned in an earlier thread, and they're not going to be open on Turkey Day this year. Help! And, thanks in advance.
