Flutterby™! : General Tso's Chicken

Okay, totally off-the-wall request: Anyone have a source for General Tso's Chicken near the Moscone Center, preferably that'll deliver? Henry's Hunan doesn't do it, and all of the other asian places of note I can think of in that area are Cantonese, Thai or Vietnamese. And I've no clue where to start looking if I go as far astray as Chinatown, as it's a dish I wouldn't normally seek out.

I'm helping some folks set up for Linux World Expo and they've made a request for Monday lunch, and I'm having trouble tracking it down.
