I'm basically looking for prepared food that only needs to be warmed, not a whole turkey that needs to be cooked. Turkey, nice variety of sides; we'll get dessert elsewhere, so that's not a requirement. Only need to serve up to eight people.
Ideally, the place will be in Bethesda (or Chevy Chase) and preferably open Thanksgiving Day. Cost not really an issue, but not necessarily looking for fancy, more just high-quality and simple.
