I am a sucker for pizza. zpizza has vegan offerings in addition to meat and cheese options. My meat-eating friend said her pizza was excellent.
I enjoyed my pizza. Not the best I have ever had, but worth eating. I also got a salad that was much bigger than expected. I had taken bites of both before remembering to get a photo. The Berkeley Vegan pizza and California salad with Italian dressing, the only vegan dressing.
If looking for pizza in the downtown San Francisco area, zpizza works well. I give 3 out of 5 vegan cupcakes. Good, but not great, and would go again.
