On our trip, we went to the Aw Taw Kaw Market (aka the Marketing Organisation for Farmers) to take a look. I read that it was a food market so we thought it might be interesting to visit.
Saw lots of food stuff, cooked and raw but we didn't really dare to try the food though. We bought mangoes from here to take home though.
Hoops & Yoyo with Mangoes
Loads of garlic!
