Honestly I can't remember. It's been a long time since I've been there as well. But I do know that I went with a large group...about 10-12 people or so...and some of them can be rather cheap lol...so I imagine entrees weren't much over $15-20.
It's in the 15ish range for the less expensive entrees. I can't think of anything worth eating in Georgetown that's filling in the 10 dollar per entree level- I can, however, once you move a little closer to DuPont.
