TCHO: San Francisco's Willie Wonka Chocolate Factory (VIDEO)

Ghirardelli may be San Francisco's best known chocolate, but production moved away years ago. Today, TCHO is the real San Francisco chocolate -- and it's the only place in town involved in the entire chocolate making process.

You can also -- and too few people know this, says Antonio Barrios, chief concierge of The St Regis San Francisco -- take a tour of TCHO's artisanal chocolate factory, right on the bay. It's an insider's look at how chocolate is made from bean to bar, and includes plenty of taste testing -- all in the name of education, of course.
