This press release from 2009 explains the difference in the gluten free from a regular Uno's pizza, that the French Meadow crust are round and thin crust, not a flat square crust like the regular or deep dish.
They don't have a wide variety of pizza options, but the basics are covered. The nice thing about their menu is there is more than just pizza. So you have options no matter what mood you are in.
Recently while traveling we noticed a Uno's Bar and Grill sign near our hotel. We decided it was a good dinner to order in. I was very impressed that all our food was in one back, and the gluten free pizza was packed all by itself. Yay; They understood!
One of my other favorite dishes there is the Baked Chicken Spinoccoli, how can you go wrong with chicken, two types of cheese, broccoli, spinach, tomatoes, garlic... Yum! They have more than just broccoli as a side, so I am willing to stop here for a quick meal since everyone can find something they like.
