Ok, there are two problems with this place.  First, the food.  It is only ok.  The fries are quite good, the hamburgers are serviceable.  The shakes are pretty tasty, but not noteworthy.  If you go, you are going for the fun theme, right?  The place has a weird vibe.  There wasn't much energy or fun happening, at least when I was there.  \nOverall: Ok, not great.  Oh, I felt like I had eaten a bag of cement about an hour after drinking only 1/8 of the shake.\nOh yeah, cash only.
