Back on topic (finally) - I had a delicious slice at a place I had previously overlooked called Pizzeria Avellino in the Marina. It's around the corner from Liverpool Lil's and across the street from the Presidio Lombard Gate - 2769 Lombard St. Thin, crisp crust but not cracker thin like Nizario's, good amount of cheese and toppings and everything tasted fresh. I had a mushroom and pepperoni. What I liked best was the sauce. It was very similar to Toto's which I think I mentioned has my favorite pizza in the Bay Area. I'm going to have to go back with an appetite and sample a few different slices - I just stopped in for a snack on the way to Tony Niks in North Beach. It's a small place and I can see it filling up quickly at peak hours but they also have picnic tables outside. Another plus is that you can BYOB from the liquor store next door!
