Suggestions - staying at 38th and (i think 9th) over Thanksgiving weekend
You will be pretty close to Koreatown, so do a search on this board for previous threads discussing Koreatown options. Madangsui (preferably for galbi/bulgogi) and Don's Bogam are my favorite Korean barbecue places.
I also agree with pbjluver on Hell's Kitchen: Just walk up 9th Av. to the 40s and 50s. Do a search on Hell's Kitchen, 9th Av., and pre-theater for relevant threads. Lately, I've been really liking Gazala Place, a little Druse Israeli restaurant on 9th between 48th and 49th:
