I've never had it but I imagine it to be excellent. But one of us needs to try it to find out and I won't be in Chicago for a while.

They also have a full lunch menu available (sandwiches, salads, etc.) all very reasonable. Reading a few reviews online, they range from "ok" to "good"... so at that price point, I think it's acceptable for the view.

I suspect there aren't many people who want to trek up there during a weekday lunch. It's not really a business district and there's some time involved with getting up the elevator.

Another option would be to have appetizers in the bar area. They're all overpriced but decent. You could call an audible when you step off the elevator.
