I used my promotional letter (one free dish) and tried the Northbrook location for dinner tonight. In a nutshell, it was ok. As many others have stated, while the food is of a different skew, the overall experience is very Chipotle-like. The space was bright and clean. Prices were fairly reasonable, with sandwiches at $6.50 and entrees ranging from $6.50 for chicken to $8.50 for salmon (which we did not try).
My favorite item -- by far -- was the Venetian plate with Steak Roti. I implored the friendly counter guy to cut it directly off the spit (rather than scoop it from the hotel pan on the steam table) and it was worth the polite, minor resistance I encountered. The steak was really well charred, moist and had good flavor, even if it was a bit salty. Nothing about it struck me as particularly Mediterranean but it was good on its own terms. Chicken Roti, which we also tried, was not nearly as good. We were told that the spit containing it was not fully cooked, so we had no choice but to accept the steam table inventory, and the texture was uniformly soft. The flavor here was also pretty bland. It really paled in comparison to the steak.
The plates came with some salads, which were ok: hummus, baba gannoush, Israeli cous-cous and tomato-cucumber salad. While it was easy to assess the meat on its own terms -- I'd never had Roti before -- it was impossible for me not to compare the salads to other versions, and these came up pretty short. I thought the hummus lacked depth and banged a one-note acidity that overwhelmed everything else. The baba conveyed some smokiness and I actually liked the somewhat dry texture but it had a sweet finish, which seemed out of place. Cous-cous was perfectly fine -- and I was happy to see such an uncommonly found item -- but the flavor was not to my liking. The lightly vinegared tomato-cucumber salad just seemed like a dumbed down version of Jerusalem salad and it made me wonder -- as I always do -- why, in Janauary, anyone even bothers to serve fresh tomatoes. These tomatoes were, unfortunately, not exceptional in that regard.
The Gibraltar plate was comprised of the same salads that accompanied the Venetian plates but with cold, grilled veggies in place of the meats. The vegetables were, for the most part, tasty and nicely crunchy. My personal preference would have been for more eggplant and squash and less bell peppers but some folks like bell peppers and at least there was a nice section of red in addition to the obligatory green one. The mushrooms could have been more cooked but that's a minor quibble.
I really didn't care for the falafel, which was extremely soft and creamy (i.e. mushy) on the interior. The flavor was decent and the thin, outer shell was pretty crisp for falafel that had been sitting around for a while but I couldn't get past the interior, which just wasn't right, IMO. It was more of a croquette than a falafel. I chatted with the owner and the (executive?) chef about this on my way out. I asked if this was intentional, because I've eaten quite a bit of falafel in my day and never encountered that texture before. They said it was, and asked if I liked it. I admitted that while the flavor was good, it wasn't my cup of tea. I prefer a drier, more granular interior. The owner then asked me if I liked Pita Inn. I told him that I liked it very much and he told me that Roti's falafel beat Pita Inn's falafel 92-6 in a taste test. I was so stunned by this information -- because Roti's product seemed like a blown batch to me, relative to Pita Inn's (which isn't even close to my favorite) -- that I couldn't even muster a follow-up question.

I tried 2 sauces and again, neither transcended. The tahina was very thick and I wished I had some lemon juice to stir into it. The "very" hot sauce had a wee bit of bite but it was tomato-based, so there was a definite ceiling on how hot it was going to be. Because of its color, it resembled something I thought would be much hotter (like harissa) but it was just spicy tomato chutney.
Would I go back? Yes, because I think their food is whole and relatively healthy -- and the steak Roti off the spit was very tasty. But it's not a place I could ever see craving or making a destination. It does seem to aim for the middle of the road and because of that, it seems somewhat devoid of soul. There's absolutely nothing funky about it (which might be a positive in some eyes) and while right now there appear to be only 2 locations, Roti just feels like a chain, where standardization and reproduceabilty are more important in the overall scheme than actual food quality. Still, in the intersection between what they are doing and what I typically seek, there is a time and a place when Roti might be the right call.
