Brunch might be the best in Champaign-Urbana area. 5-stars. Beer-bread toast is thick and incredible. Omelets are over-stuffed and innovative and completely satisfying. Regular specials make some variation on the menu. Coffee is aromatic and high quality. Wait-staff at Radio rarely makes mistakes: they're natural and easy and very good.
As for other things, their beer selection is as good as any of the craft beer bars in downtown Champaign (Blind Pig, Quality, Big Grove, etc) but I often forget about it as a choice.
4-stars overall only because the tapas menu, while tasty, can get really pricy for the portion sizes. This is what tapas is about I suppose, but also means I don't choose to head here in the evening as often.
