My comments will echo that of a fellow Yelper - I think your opinion of Gigi's will be largely informed by what you think of their sauce; if you like sweet, you may enjoy it (and potentially this place), but if you prefer savory (ie. garlic, herbs, classic Italian seasoning), forget it.
For me, the notes of cinnamon/nutmeg/allspice (coupled with plain sugar...?) in the sauce was a complete turnoff, as was the carb-bomb of a crust that will sit in your stomach like a brick. The toppings are fresh enough but in no way innovative or refined - this is very much nondescript/uninspired pizza that will fill you up if you're hungry but hardly wow you as being anything remotely out-of-the-ordinary (barring that polarizing sauce).
