Is this place good for just a fun climb for people who don't do it much or is it for more serious climbers?

Good for a fun climb, but with LOTS of kids in the evenings/weekends

I'm fairly new to climbing and ug has been very good for me

There are less expensive gyms to try for beginners, but they have a healthy staff that can offer tips and have a lot of route options. I'd you do go, do so understanding that they do not represent the standard gym experience, and they may say things are typical when they are not.

I'd say this is more of a beginners gym. If you want more of a high level gym, which it doesn't sound like you do, you'd be looking more for Movement. Evo is a good midpoint.
