100% completely underwhelming. I didn't want to rate it 2 (Meh. I've experienced better) but I even more so didn't want to rate it 3 (A-OK.) I don't consider this place to be A-OK, more like completely average.
The atmosphere is much larger than I thought it would be and is all counter order. They get packed for lunch and have lots of Chicago shit on the walls. It's a good enough place.
My Gyro Feta came with stale pita bread, too many giant slices of red onions that overwhelmed everything, and pretty much just seemed like something I'd find in my cafeteria at work. The quality was crap and it was $6.45. I could go to Cyprus Pita Grill and get a really good gyros for the same money.
