I came here because of the positive reviews here on Yelp, and Yelp, you let me down...
I forgive you though, because generally you're spot on and I love you!
That said, I only tried O.G. once and it was only the chicken kebab sandwich, but it wasn't good or pretty or tasty. The whole sandwich was pretty bland and the onions and tomatoes were huge chunks I could barely get my mouth around (they were bigger than the chicken pieces). It was so wet that the pita turned slimy and soggy in the 1-2 minutes it took me to take it outside to unwrap and eat. It also dripped everywhere. :(
I couldn't eat more than about half of it (some of the chicken, a couple of tomatoes and the edges of the pita). I wasn't that sad, but I was still hungry. Don't worry, Chicago Gyros, you're still my #1 spot for Greek!
