My family has lived by the market for over ten years, and we shop there at least a couple times each week.
There's the original market that is housed within a building structure. The vendors occupy permanent stalls, and you can also find a number of nail parlors, skilled seamstresses, and stands selling prepared foods in addition to the meat, fish, veggies and dried goods vendors typical to wet markets. But the original market has lost much of its crowd to the open-air market across the street where new and colorful merchandise is always rolling through. Territory is not as clearly marked out in the open-air market, any bit of ground space clear of foot traffic can be claimed to set up shop. Don't be surprised if you can't find the same sesame candy cart on your next visit.
Prices are not always better out in the wet market though. I'm local, and I've still gotten ripped off a number of times. There are still better deals and greater variety in the supermarket just across the street-- at least for produce. The wet market still makes a fun stroll.
