Just before the Bell Brothers concert. I ordered a small chai latte, and each of the kids wanted a taste. They ended up drinking about 2/3 of it.
So I bought myself another one, and they drank a lot of that, too.
Nonetheless, I figure that even with buying them dinner there, dessert, and drinks, it was less expensive than going to the movies or Great America or any other place we normally go that doesn't have a family membership.
