This is definitely a novelty place. And as far as novelty restaurants go, it's a great one! It's definitely an experience eating here. Every customer has to put on a hospital gown to enter. All the employees are either dressed as nurses or doctors. When you look around and see everyone consistently dressed as if they're in a hospital, it really gives you that novelty experience.
If you don't finish your food, you get spanked by a waitress with a wooden paddle. And they hit HARD! I was expecting it to be a cute little tap, but they really do wack you. The fact that you _have_ to get a ton of food and are actually thinking about the fact that you will be spanked if you don't finish is definitely a unique experience.
It's also fun when a 350+ pound person gets up on the scale in the middle of the restaurant to get a free burger, and everyone cheers.
I just got a single bypass with extra bacon and fries, and was a bit underwhelmed. The taste wasn't distinguishable. It tasted like an average burger and fries. I tried some of my friends chili though, and that had some good flavor.
Note: to my surprise, there were a lot of families/kids around. I was confused about what the kids could eat - a full half pound burger seems like too much - but they let the kids share and I suppose it's a fun place for a kid to be.
Conclusion: Clearly it takes a certain type of person to enjoy this atmosphere. I'm going to assume that you're that kind of person (otherwise, why would you be reading this). With that assumption, I think this is a good choice if you want an experience to remember.
