Flutterby™! : underground food

An SFGate article about underground restaurants:

"It's sort of an anti-restaurant," said Townsend, 29, a poet, promoter and former boilermaker and South Pole tunnel digger who has amassed an e-mail list of 1,200 interested parties. "The restaurant experience is very stale. People are usually disappointed, or at least not awestruck."

That goes for chefs as well, some of whom moonlight at these illegal ventures for either a creative escape from restaurant rules or a way to fulfill their dreams of opening a restaurant -- without actually doing it.
