I had lunch here Friday as I was coming home from Omaha. Not bad! I got there about 1000 and left about 1100.
I got the Stanley Burger, which is apparently named after a Chicago Cubs player or someone else affiliated with the team. It’s a half pounder with a thousand island based sauce, bacon, and the usual toppings. The burger was pretty good; decent beef and cooked medium well as ordered, with a nice crust and just juicy enough. I got fries for the side, and the iced tea was very good (a pleasant surprise).
Service was a little slow on occasion, but mostly OK. My check was $18.33, about what you would expect for a restaurant at an airport. You could certainly do worse when passing through O’Hare Terminal 3.
