Totally a novelty, go there only if you want to say "yes, I've been there". Sundaes are pretty good, and HUGE but nothing outstanding, and not worth the $15 each. Big enough to share, possibly for three people, too. The fried oreo sundae is really good. There is always a wait to get in, and they close pretty early so if you don't get there early enough, they will tell you that they cannot get you in for that evening. Blows my mind that a mediocre restaurant in Vegas actually turns away business.
