My grandparents are long-time fans of the Ribeye, and I have joined them at the Ribeye on two separate occasions. Both times, the hostesses and the servers were extremely nice to them - treating them like local celebrities - and anyone who is that nice to my grandparents is okay with me!
The Ribeye has a relatively limited menu and their specialty is the ribeye (surprise, surprise). The salad bar and baked potato are included with the ribeye dinner, and both are pretty good. The overall ambiance of the Ribeye is relatively casual, and they have a lot of Fighting Illini memorabilia. I think some of the reviewers who were disappointed with this place may have been expecting something along the lines of Morton's or Gibson's in Chicago - the Ribeye is not that.
