I've got a large group (~30) going for lunch somewhere near Hayward. There's a number of good places nearby, but I can only think of four nearby that can handle large groups:
Han Yang BBQ in Hayward
Little Sichuan in San Mateo
Copper Chimney in Union City
ABC Seafood in Foster CIty
Any other ideas? Most of the other buffet style places nearby that I know of are so-so or outright bad.
