Would this place be good for teenagers/ young adults without children?

Yes

It sure would be. First time I went was well before marriage and children and it was a blast.

Definitely... kids of all ages can enjoy themselves whether it be video games and laser tag inside or go karts and miniature golf outside. There's also food and drinks as well.

Yes, it's great for teens. It allows them to have harmless fun. That ranges from arcade games that are too loud to go carts that seem like they might just be too fast.
