It's pretty fantastic!
The 3 star rating is for it just being a mixed bag in all kinds of ways.
Large variety of items, reasonable prices, and real gems! We went looking for some sun shades for the car and found plenty. There's a lot of neat trinkets and such that you wouldn't find anywhere. Also found some interesting food choices (try that chocolate crepe kebab thing. It's UH-MAZING). However.. you also have some pushy, inattentive shopkeepers, rude swapmeet patrons, and everything seems a little disorganized. We got lost a few times circling around looking for the shop we passed. Yeah, I understand it's a swapmeet, but there is no excuse for being straight up rude. This ain't Wal-mart!
Overall, would come back if I was looking for some cool gifts or possibly Chinese plants.
