You can also call ahead to organise a personalised chocolate tasting to be done at The Chocolate Garage. :) We carry a diverse selection of Happy Chocolates and are open by appointment. We specialize in chocolate tastings and have a "try before you buy" policy.
And, I would also strongly urge you to stop by Monique's Chocolates in Palo Alto, two blocks from The Chocolate Garage to sip on one of their "to die for" hot (or cold) chocolates. Or taste one of their many single origin confections. Mark West is very knowledgeable and happy to talk chocolate.
Chocolate is booming in the Bay Area. :)
