A great friend of mine who lives in DC will be up for a night next week and wants me to take her and a few friends somewhere cool in Chinatown. She loves funky places (though it usually means I can't make a reservation, but that's okay) and I've had success in the past taking her to NY Noodletown and New Green Bo. I'm thinking maybe Joe's Shanghai but could anyone come up with perhaps somewhere less obvious? It doesn't have to specially be Shanghainese--just delicious and unpretentious with some unusual food as well as familiar stuff. Thanks in advance!
