You can find a vast array of merchandise from anti-mosquito cream, sunscreen, as well as some snacks and drinks there. We highly recommend you to try the delicious “bánh giò” (pyramid rice cake with pork) or “bánh bao” (ball-shaped bun containing pork)!

*Note: Price of goods in these stores is a little bit higher than the market but still affordable.
