Went for the Chicago style pizza. Check out the pictures I uploaded.
The staff was very warm and friendly, and provided excellent and fast service. Such good service is rare these days so extra points for that.
The Chicago style pizza had about 2 inch sides and a relatively thick (1 inch) crust for Chicago style. True Chicago style is not thick crust, however this crust was soft if spongy and the slice was not rigid. Look at the picture to see what I mean. The sides of the crust were crispy but relatively dry and did not have a particularly buttery taste.
The toppings were good and spread evenly throughout the pizza.
The sauce was quite balanced, bordering more on the tangy rather than the sweet. I do think the pizza was a bit light on the sauce.
Price was about $20 for a HUGE and very heavy 16" Chicago style pizza, not unreasonable considering the pizza weighed almost 7 lbs, easily feeds 3-4 people.
Overall this place has great service and very friendly staff (a rarity these days). It is one of the few places in the valley for Chicago style pizza and one that doesn't disappoint. However, I do think that Amore is still the best Chicago pizza in Las Vegas.
