The Green Shop (กรีนช๊อป) is just a little shop next to the lake at Green Lake Resort on the canal road. It doesn’t have a huge range of stock, but does have everything that the many local anglers who fish the lake need. It sells lower priced rods and reels (each around the 300 Baht mark) and has a decent range of bits and bobs. It also has a fridge with beer and soft drinks – great if you are fishing the lake; the shop next door sells cooked Thai food.
The bait they sell for fishing in the adjacent lake is not the regular rice bran, but actually a powdered fish food (it’s a brown powder in a bag). This seems to be the bait used by most people fishing there.
