My family will be meeting in Cambridge for Thanksgiving dinner and I'm in search of restaurant recommendations. I live in DC and know very little about the dining scene in Cambridge. A friend has suggested The Harvest and Henrietta's Table. My family is from rural Minnesota and would be pleased with anything more appealing than a Perkins or Applebees (the only options in their town). We are looking for a traditional meal in an upscale setting with turkey, dressing, cranberries - the whole works. Any ideas for a group of 6?
