This Chocolate Salon event is coming up on March 15, 2014. It's going to take place in San Francisco - http://www.meetup.com/chocolate-69/events/155256912/
We arrived at Fort Mason Center and discovered these two food trucks parked at the entrance. It was still early so there was a short line. However, at lunch time, the lines were much longer.
A sign at the entrance.
Neat interior architecture which was unexpectedly modern.
