When you talk to her at school, kind of in a general conversation without being too direct…tell her your boss mentioned he thought it was a cool, but you’ve never been…ask her if she has. If she has she’ll likely offer her opinion…if not, then describe to her like you did here…pay attention to her response. Then you’ll know for sure if it’s someplace she’ll enjoy or not. 
PS: That suggestion is based upon it’s important to you that she enjoy where ever you’re going…it should be important too though, that she have an interest in going someplace you will enjoy too. Inside the mindthought of a woman…If you indicate it’s someplace you’d like to go by bringing it up, saying you heard it was cool…she should pick up on that, and if she’s not totally self absorbed…she should have a positive reaction for the mere fact that it’s of interest to you, & she likes you, so your having a good time is important to her too.
