Hookers Sweet Treats for salted caramels and bread pudding
Despite its tongue-in-cheek name, this sweets shop and cafe located in the gritty Tenderloin district is one of my favorite finds in San Francisco.
The salted caramels here melt in your mouth. They also have a good variety of coffees from Sightglass Coffee. It's quite a charming place in a place you wouldn't expect.
