I went with a group of friends a week after they opened on a Friday. It felt like they were severely understaffed, and many of the employees kept telling us they're just figuring out the flow and pace of things. We got there around 6:30, seated at 7:30, ordered drinks at 8:00 and our food arrived 40-45 minutes later. Our two appetizers (Samplers) got us through the wait, finishing our meal around 9:30.
I've had Giordano's in Chicago and for me, pizza doesn't differ too much from place to place. The pizza crust was thick and each slice had a LOT of cheese. I enjoyed the vegetarian pizza immensely, with layers of spinach in between the crust. The Meat Lover is not for the faint hearted with sausages crammed in the bottom crust, topped by more cheese and meat. The clear glass panel that lets you see into the kitchen is entertaining.
