Recommend Chinatown eatery that will...

I have a friend who is allergic to shellfish but wants to go with us to Chinatown because her husband wants to go.

We frequent this forum's namesake, Moon Palace, Spring World, Lao Sze Chuan. But I'm scratching my head wondering...is anything we've enjoyed there shellfish-free? I'm thinking about dried shrimp, d.s.-paste, oyster sauce, etc. I think the noodles at SW might have been - noodles with ground pork, black vinegar, etc.

Any recommendations? Or do you recommend one of the places I could call ahead for some crustacean-free dishes? Thanks.
