Where do young adults go to hang out on weekends - or what do they do with their weekends?

By that I mean people in their 20s and 30s. I have heard Kava bars but there are so many in the area to choose from. Are there any specific ones that attract that age group? Are there other places besides Kava bars? Maybe something like a running club, art classes, kayaking - no idea what people my age do here for fun. I moved here from Colorado where it felt so much easier to meet cool outgoing people my age and make friends.
