The area in Yangon where you can find all things Chinese. The sale style of the shops are pretty old fashioned, where dried goods are sold from the gunny sacks and salted fish are homemade. Some stalls do not have fixed price for weighing and selling fruits, so be used to paying for fruits according to that "handful" or approximate "size".
Measuring weights come in the form of weighted round discs and levered measuring plates. Very much old Southeast Asian style.
There's also plenty of clean, interesting streetside food stalls for you to try out local snacks.
