I feel like putting edge is still stuck in the 90s, which gives it kind of a retro ambience. It's enjoyable for adults for this reason and enjoyable for some kids (under 10 I'd say).
I've been here several times with volunteer agencies and it's a mixed bag in terms of the enjoyment factor for the kids. If they're young enough, they're still entertained by it. A bit older and they think it's super lame. The glow-in-the-dark aspect it what makes it cool and they post fun little tips on the wall to make the game more interesting (hold the putter backwards, use it like a pool cue, etc).
It's a bit expensive for what it is, especially considering it really only takes 30-45 mins to get through the entire course.
Still seems to get a lot of birthday party business though (even on a Monday night) so they're obviously doing something right!
