Tartine Bakery & Cafe.
Tartine is one of mine (and many others') favorite bakery/cafes in San Francisco. They're known for their delicious pastries, hot pressed sandwiches and especially the 5pm daily fresh bread sale. We took some of Chris' Los Angeles friends there for lunch when they came to visit. One of the best things about Tartine is its close proximity to Dolores Park and the DPT's allowance of parking illegally in the middle of the road (only on Sundays). My mouth is watering just thinking about the lemon tart!
