I'm giving this 5 stars for the value alone.
The UYE to do all 7 buffets in one day was fun with other Yelpers, but it literally made me hate looking at food for the week afterwards.
Yes, I gained a little weight from this event, but afterwards when you can't even look at a menu in a restaurant without feeling bleh, you lose the weight pretty quickly. The next day after this event I had to go to a dinner with a friend that was in town, and I had problems just ordering anything after not eating all day.
I would recommend doing this for 3 meals, not the 7 that I did. Unless eating at all 7 is on your "bucket list," then I say go for it.
