pizzaiolo has the best (not fast food tasting?) pizza of any of the pizza chains. Their sauce, cheese and bread is all of much higher quality than the other chains. They are more expensive but the price is worth it.
whatever my toppings it tastes like actual food and can make a (sort of bullshit, still nice) romantic dinner if you get a pizza and a nice bottle of wine.
This is what I do for my romantic dinner when I have my anniversary getaway at the westin (3 topping large pizza 23$, hard to beat when it costs that much for a yogurt at the hotel)
This goes for all locations, I think this is the one I order from when I stay at the westin. They also have amazing customer service that is consistent at all locations.
Without a doubt this is the best pizza chain.
