Pretty new place on The Corner (or just off it, depending on how pure you are): Roots Natural Kitchen. As one can surmise from the name, it's predicated on healthy stuff. Given the location, it's catering to students (and faculty members, such as I). The prices are good. Parking is the usual Corner hassle (though not so bad during these summer months—and take the trolley!).
I've only been once. The food was O.K. I had a standard dish ("Mad Bowl," which is a bit of inside joke) and my date created a custom bowl. You can design the order, which is probably the way to go. More tests will follow. The concept could work out well, as the paths toward different cuisine-flavors get refined.
Just east of the railroad underpass on University, almost across from the George Rodgers Clark statue.
