I popped into this AP location in the days following Christmas 2008. I'd purchased a few items online prior to this and was a fan of the merchandise already. It's pricey (at regular price, at least), but it's a nice occasional treat to give yourself (or your special someone).
The sales associate here was friendly and helpful, but not overly so. I think she realised that I was going to drop a good chunk of change so she sort of kept showing me stuff, but didn't go out of her way to be helpful other than that. The store is very clean and well organized. The dressing rooms are spacious enough to comfortably get in and out of everything and the sales girls know their merchandise well.
I spent nearly four figures and got three sets of lingerie. The nice thing about most of AP's stuff, though, is that it isn't just for show. It's good functional lingerie, so you can feel a little better about dropping a fair bit of cash on it.
