A big-box all-in-one store much similar to a Super-Walmart, but with a reverse emphasis on grocery vs. everything else. Buses from the local UIUC campus stop by on the street. The lines here can be incredibly long. Unless you're here at the super-late, post-family line times after midnight.
The groceries here are sometimes cheaper than other locations, and certainly well-stocked with food you probably should eat less of (snacks and ice cream, noticeably), although partially to cater to the student population, I think.
Overall not bad, they generate business by being the one-stop for almost everything, but they'd probably be better off with speedier lines.
