The only Build-A-Bear! workshop I've seen is at Ontario Mills and I'll agree, it's ridiculously cute and ridiculously expensive. I've never done it myself but I've been inside and looked at everything. The one thing that I found odd is that the shop is actually really demented when you think about it, for instance, in the big machine where you fill the bear, there is some bears stirring up the innards of their bear friends.

Scary ;(
