The store at Pacific Mall is not only bad, it is to be completely avoided. Period.
6mm has a spotty reputation. If he's there, good luck.
In a nutshell, no stores to look at. If you want gear, find army surplus stores.
Pacific Mall, as said, is quite the experience. I describe it to my friends like this; you just stepped into Hong Kong or some place else in Asia. It's a culture shock, but a lot of fun.
