My family often gets rosati's on birthdays!! Their pizzas have always been really good and their deep dish pizzas a freaking delicious. They are really filling. We have gotten a "meat lovers" deep dish pizza and a bbq chicken pizza there, along with other pizzas at different times. But those two have been the family fav.
Never have had any problems with delivery. Sometimes the deep dish take a little longer to make but still, worth the wait. Especially if you're having a party the wait doesn't seem as long. The pizza is good. It's worth it in my opinion. So if you want good pizza go there. Get the deep dish. It's fun and typically unusual to get deep dish. So have the experience.
