Informal Birthday Dinner- Quirky Suggestions?
I assume you mean somewhere in the Wilmington area (let us know if that is not correct!) I wish "funky" were a part of the landscape here, but sadly, it is not. For true funkiness you will probably need to go to Philly.
If I had ten people going out to dinner, I would make a reservation for a big table at a Korean barbecue. Kahl-Bee Korean can accommodate this (I haven't tried the other Korean place in Newark but it is worth considering). This kind of eating is fun for everyone and works best with a group. You can knock back a lot of beer with Korean food, too.

Margaret Kuo's Peking in the Granite Run Mall is a little far but the great place to go.
Sushi there is NOT the reason we go, but Chinese dishes are excellent. We always get Peking Duck special complete with all the trimmings, Chef will demonstrate trimming right in front of you.
