We've been a few times and it's pretty fun for a good wholesome activity. The first time I got out on the ice I couldn't stop grinning I hadn't skated in 10 years at least.
It's pretty pricy compared to the public rinks back home, but for the fun we have we can afford $14 for a 2 hour session. It's $3 extra to rent skates, and they may not be very sharp, it's kind of a crap shoot there. This last time I asked for their sharpest skates and they got some down from the very top shelf but they were still pretty dull. BUT, if you have your own skates or you're too much of a novice to notice whether they're sharp or not, this won't be a problem.
We got my son his first pair of skates, ordered from overseas of course since they don't sell tiny skates here, and we tried them out yesterday. A good time was had by all.
