Went to the Carbondale, Illinois Steak n Shake had to walk on a wet floor, was seated an notice a horrible smell. Was told there was a leak be the soda machines. It smelled like someone had thrown up. By time we got our food it was over cooked. Went to pay and there was a line and no one to ring us out. Server's just looked at us and didn't do anything. My dad asked for the Manager, when she finally came out she wasn't smiling or even friendly. We paid for our meal and left never to return again.
