So let's say there's two scenarios here that might be relevant to you:
a.) You're a big KISS fan staying in Vegas and looking for something to do after partying hard - Monster Mini Golf is for you.
or
b.) You're partying hard in the Hard Rock and in a drunken stupor, come across the strip mall across the street and see a crazy KISS vehicle and come in.
If either of these scenarios pertain to you - you're in the right place most likely.
Monster Mini Golf is literally a glow-in-the-dark mini golf course, arcade, and memorabilia locale which is all KISS themed. It's really kind of weird yet all so fascinating whether or not you're a KISS fan in general (unless you really don't like KISS stuff). I don't think this will be everyone's cup of tea and of course, your mileage will vary but really, for like $12 for a game/beer and just seeing it for yourself - it's kind of a trip in itself.
