I was at a Rocky Roccocco's a few weeks ago. They are starting to make a comeback. They have changed alot. Now they specialize in combo meals, I'm sure you can get a full pizza, but they specialize in pizza by the slice. You walk in, and its overly bright and colorful, almost like a subway or quizno's. No pizzeria ambience. Its been about 15 years since the one I was close to went out of business so I am not real sure if the pizza is the same or not. Pan like in appearance, very greasy, and their breadsticks is very "crazy bread" like in taste.
I don't know where you live in Chicago, but the one I went to was in the suburb of Algonquin, on Randall Road off of I-90.
If you check the web, you can probably find one a little closer to Chicago.
Its funny how franchises expand and contract. All the domino's pizza's & little caesars went out of business about 10 years ago in my area. Now 3 domino's & 2 little caesars just popped back up within the last year, with a new look & new menu.
