I heard about this on television as one of the places to try in Las Vegas...I think not.
Their burgers and french fries are cooked in lard. When I think of cooking with lard I would imagine it to be super greasy but really good. This was not the case. I got the one patty burger. The size was good, typical toppings but bland bland bland. The french fries were bland and super soggy. My friend tried one of the milkshakes made with butter. I didn't get to try it myself but he said the solid chunks of butter you get in your mouth is not pleasant.
The only part that I enjoyed was the theme of the restaurant. You get to wear hospital gowns and you don't have to worry about getting your clothes dirty. If you want to check it out, come for the experience, not for the food.
