You know I was just thinking "Wow I sure hope the next FPlus Live is in Portland..." and here we are!
If you're looking for karaoke places nearby...ish, I like Voicebox PDX, always have a good time there. I would be down for hanging out with other people in other places in the city as well! My partner isn't a ballpit user, but she's also a huge fan and would hang, too.
