Ideas for a hangout with another mom

There’s a mom I really like talking to when our kids are at the same activity, and I hate that we only really ever talk when we are at obligatory events. I don’t really have other mom friends and don’t really know what mom friends do together, so I’d like recommendations for your favorite thing to do to get out of the house with another mom friend! Bonus points for ideas that are cheap and not centered around alcohol. Thanks in advance, can’t wait to hear your creative ideas!
