No toppings. I wouldn't buy the round pizza (it's VERY ordinary) and the square certainly doesn't need any.

It's gonna be a nice day so be prepared to put up with a crowd (but it's worth it). Grab an outdoor table when you get there, and have someone order the square pizza at the window to the far left (as you look at the place). You shouldn't have to wait more than a few minutes. IF you eat inside (waiter service and a complete lunch/dinner menu) you can still order square pizza and enjoy it a little more leisurely.
