Difficult to find...take the elevator up to the M level.
No decor inside...feels like an old cafeteria, and the location sucks, but the food is really good...it would do amazingly well in a better location.
I went for a workday lunch; very good menu and my friend raved about their Turkish pizza. I'd recommend ordering online/ordering before you go, or else you might wait a little while. I got their grilled chicken salad and the chicken they had on it was some of the best I've had downtown.
