If you are just seeking the meal to be cooked ahead, and don't need servers or specialized menu, ShopRite ,and I will bet other grocers, offer service for thanksgiving. Word of warning though, it comes cold, and will need reheating. They usually start to advertise it in early November circulars.
I have seen advertisements in local restaurants (definitely Park Wood and probably others) as well as Kings in the past.

It's a little early but have to think ahead...Is there such a thing? We are going to have a celebratory family party in November and have considered combining it with the turkey day meal. We would like to make it a little special and different by having it catered. Can anyone recommend a business that would do this? Thanks in advance.
