Time Out says
Many are drawn into Kum Wah by the buttery aroma that spills out onto the street, and there is not a time of day when a crowd can’t be spotted outside buying the freshly baked goods. The most popular item on the menu is the pineapple bun served with a slab of butter inside. With its crispy, sugary top, and the fluffy and sweet bread underneath, the bun is so popular that it’s not unusual to have to wait a while for it. $70.
