I've seen folks with kids stop by the kiosk before. Its pretty quick to pick up to-go bottles. I've actually seen families eating there too, although I wouldn't call it family friendly or recommend eating there if you have kids.
It's fairly easy to find these days. Distro is mid to end of the week depending on the distributor and it get's picked up pretty quick but not out of the question you'll find some, if you hit a few stores. If you don't find Zombie Dust I'd recommend about any other 3F's, you can't go wrong.
