Oh no. A tipster tells us that the Pacific Heights Bittersweeet Chocolate Cafe, a great gem that focused on "small batches, custom roasts and responsibly grown cacao" closed shop without any warning.

Our tipster writes:

Drama in Pac Heights. The owners of beloved hot chocolate purveyor Bittersweet told their employees yesterday evening that it was their last day in business and loaded up a truck and disappeared. No one had advanced notice, according to one of the employees.

SFist talked to an employee at the Rockridge location. He confirmed that, yes, the Pacific Heights Bittersweet is no more. Alas. But, he went on to tell us, they plan on opening a shop in Jack London Square soon.

When asked why the owners closed shop so suddenly, he simply said, "Blame it on the landlord."
