If the giggles seem to hit a crescendo near Water Tower Place, this is why. Unless you’re a parent of a young girl (and really, even then) don’t expect to understand the excitement that builds around this pink palace, where dolls can visit the salon, photo studio, doll hospital, or join their owners for lunch, afternoon tea, dinner, or even a river cruise. Many of the dolls are modeled after historical figures, and despite the opinion I have about the high prices ($110 for a doll and a book, are you kidding me?), at least American Girl moves us away from the dysmorphic Barbie doll.
