My only experience with Carl Jr's was a stop in Cheyenne about a year ago. We walked in after being on the road for 8 hours to find the men's bathroom was flooding out the door into the restaurant.
(not kidding) I had to pick up my sons and step over a floating urinal cake to make it in the door.
I'm sure the burger would have been fine under normal circumstances, but the urinal cake and that fake lemon-like smell is all I can remember of the occasion.
To this day I wonder why we even stayed, but we were a little embarrassed for them and lets face it, its hard to find food while traveling with kids through Wyoming.
Perhaps I owe them another chance at a different location
Carl’s seems to be confined to truck stops around here now.
