The food is awesome if you can look past the dirt and grime of the place. Make sure you lock your car doors when you get out and I wouldn't recommend giving the place a visit after dark.
The atmosphere is so retro and cute. My kids love this place and we usually try to go at least once every year when we visit the area.
The main thing: if you can look past the ickiness of the place, then please try the food. It is artery clogging and greasy and totally amazing.
