Neat experience for a kids art-themed birthday party
My six year-old and I were in As You Wish for her friend's birthday party. It worked out very well. The group picked out the pieces they wanted to do, painted and chatted away for about an hour, cleaned up together, and then finished with gifts and a rendition of "Happy Birthday to You". It was superb to have kids and parents playing + working together for an activity for once.
Service staff was pretty good, as well. Not as structured as I would have hoped, but still helpful. You may have to approach them if you need something. Most of the crew seemed quite shy.
My wife, kids, and I may visit on our own to do some of their glass-work options. It looks like you can do some beautiful stuff with it.
