My favorite spot for Groceries in Champaign, although I usually go to the one in Savoy more often. I think they have the best produce and more options in terms of organic food (aside from the obvious Strawberry Fields and the like). The salad bar, deli, and soups are pretty solid too. I'm a fan.
I also really love their gas program. Just for buying groceries there you can get huge discounts at their gas stations. I've gotten $.75 off per gallon a few times, it's awesome.
