Trusted advisors, what source might give me a list of restaurants in Manhattan open on Thanksgiving but which are NOT serving prix-fixe turkey dinners at seatings etc. Perhaps Chinatown and Little Italy or mundane chains but this must be onlne somewhere somehow.

Most restaurants that are open for Thanksgiving have a few menu choices from their regular menu, even if they aren't serving the full menu, with a traditional turkey dinner being just one.

Well I wouldn't look at little Italy.

But you will find some ethnic places - a variety of Asian especially - that may be open for a more casuale meal. Have a look at opentable.com to see what they're got listed.

I went to Alouette several years ago on TDay and we didn't eat turkey. It's a lovely French Bistro -- Take a look at their T day price fixe menu

How about Chinese/Peruvian? Pretty good dim sum and nouveau Chinese or Asian fusion at Red Egg - a kind of hipster place just north of Canal St. in Chinatown - http://www.redeggnyc.com/ or Chinatown Brasserie http://chinatownbrasserie.com/

both can be reserved thru opentable. Lots of NYC restaurants serve on Thanksgiving, maybe with a little more info about preferred price range or neighborhood or cuisine and we can help more.
