I really like Steak and Shake's food but the service here can be absolutely horrible, if you get any service at all.. the last time we tried to go here we were sat down and went about 10 minutes with nobody coming up to our table, we had no silverware, and as we waited another man walked up to the counter and started asking why he had no menus, silverware, or anything else so we just decided to leave. It wasn't particularly busy either.
And when I actually do get food, the order is wrong about half the time. There's one waitress who works there on weekday afternoons who seems to actually care about what she's doing and coincidentally that's when things have gone the best there.
If you're there when it's busy, good luck to you. Be prepared to wait.
