Thanksgiving dinner in Wilmington, DE
Lamberti's Cucina's is my pick. Upscale, high food quality, top service, the ambience is very nice, yet reasonably priced. I've eaten there at least a half dozen times now.
They offer Thanksgiving dinner 5 course-meal for $27.95 per guest

A day late and a dollar short, perhaps, but in case anyone stumbles across this thread on a later search -- I would recommend Longwood Garden's Thanksgiving buffet. You're seated in their gorgeous ballroom, which is in the conservatory. Buffet price includes admission to the gardens, and the holiday display is well underway. As for the food -- lots of fresh salads, different kinds of stuffings and cranberry sauces, (my favorite) their mushroom soup, salmon, pastas, carving station with ham and turkey, a mashed potato station (sweet and white with fixings), a children's station, dessert, etc., with many of the ingredients grown in their greenhouses. I'd been for their Easter buffet and loved it; this is the first time I've been in town for Thanksgiving and will be tempted to change my travel plans going forward. Yum.
