The market seemed to be open every day, but the food market was only open on Wednesday and Saturday. Most of the "shops" closed up in mid afternoon when it got really hot.
All sorts of souvenirs were for sale--T-shirts, hats, beach wraps, tropical dresses, jewelry. Prices were reasonable.
I wasn't impressed with the produce for sale, but the produce in the regular grocery stores wasn't the quality we expect in the US, either. There were spices for sale. They had nutmegs which they would grind as you watched and then bag it up for you.
Friendly people! Beautiful location right on the waterfront. Everything was very clean!
