I don't often eat pizza. I grew up eating Vince's, loved the small pizzas sold at La Pergola in the early 1980s, and have had some yummy pizza in Wauwatosa, Beverly Hills, Eagle Rock, and Berkeley. I'd like to have some pizza in or near North Beach on Saturday night. Are there a few places that serve smaller pizzas with faintly blackened bottoms? As I follow a vegan diet, places with nondairy cheese or pizzas that need no cheese are the only ones I'll end up patronizing.
