This place is COOL! It's a novel idea and it's something you must try if you like being adventurous. Yes, it's a little pricey - $30 per person for entry and 2 drinks (usually they give you 1 drink, but they were nice and gave us an extra drink ticket). They give you a huge coat and gloves to wear inside the ice cavern area where everything is made out of ice. It's ok if you get totally drunk in there though because if you drop your glass, no worries - it's made of ice! You can take a bite out of your glass, if you really want to ruin your teeth, but be careful, the glasses are pretty thick.
Being in there with a bunch of drunken people could be fun. Don't leave change on the tables though since they'll start sticking to the ice tables. I couldn't help but think of the movie Dumb & Dumber when I got there and touched the icy walls. Just remember not to lick the walls or you'll duplicate that Jeff Daniels' scene.
