Westfield Antique Mall is definitely worth checking out. I have driven by it for years and recently decided to go in. It's HUGE and you could spend hours browsing. However, I had my two children with me, so I couldn't linger for too long.
There are two floors and it's rather difficult to get upstairs if you have a stroller, like I did. I would imagine, too, that it's not really handicapped accessible.
Still, we managed to find several Pez dispensers, which is what we were looking for and the prices were reasonable.
It did make me feel old, though. So many toys that I played with as a child are now being sold as antiques! I'm only 30!
