you can get decent pizza. Salvatore is a mini chain that sprung up which does a DOC pizza that I quite like. The dough is very chewy and nice. SAVATORE CUOMO is the exact name.. not bad.
as for toppings.. it's basically anything goes.. hard to get a good pepperoni pizza.. better chance getting a potato/corn/cheese pizza..
check out Pizza-La for a good overview of the different toppings..
