My fav. of all time is in SF - cornmeal and olive oil crust - toppings are neither here nor there when the crust is so heavenly, but my fav.s are sun-dried tomatoes, feta, kalamata olives, pancetta and that sort of thing. I like fancy toppings.
Also in SF I was quite attached to the Potesto - thinly sliced roasted potatoes and pesto. Mmmmmm.
Of course where we live at the moment there're only two options - a fancy place that dh isn't so keen on and Dominos.
From Dominos I tend to go for roast chicken and mushrooms with garlic sauce on a thin crust.
