First of all ignore the misty eyed descriptions you get in guide books telling you that this is a genuine Thai night market where you can enjoy a meal with the locals. You will see the occasional Thai buying food here but they'll be off on their scooters before you can get your pad Thai back to the nearest table. This is now firmly a tourist food market. Having said that it's not a bad one at all, especially in comparison to the majority of places tourists will eat.
There is a good selection of Thai food carts and many seem to be cooking fairly authentic versions of the more popular Thai dishes. You'll see plenty of pad Thai, banana roti, chicken rice, things on sticks, etc, plus a fresh fish stall and a few 'made to order' places. The latter are good value and a better bet than the pre-cooked food. The fresh fish is also good but will set you back a little more.
It's not all positive though. As this is now orientated around tourists some of the dishes have been altered for western tastes. Some may see this as a good thing while others may find some dishes a bit bland. The other side effect is in the pricing. Dishes in general are still very cheap but some are obviously being inflated. I was charged 40 baht for a single piece of cold fried chicken at one cart. Sounds cheap enough but that's basically double priced to fleece the tourist. I should have refused.
All in all a good place to eat and linger over a beer or a fruit shake. Not the best Thai food you can get but almost certainly a lot better than you'll get at any of the tourist restaurants.
