The menu mentioned nothing more than mushrooms, bacon, and Swiss, but since the T-Bone Special ($8.95, without fries) costs a couple of bucks more than the other combo burgers, I got the idea that it might really be special, or at least especially big. The glamour shot below reveals sauteed onions, too, but the bottom photo, which shows the burger as served, is more telling: A thin patty, canned mushrooms, and not a lot on the plate for anything more than a snack.
