On the first night after arriving in Chiang Rai, I checked Tripadvisor and found this restaurant ranked first in Chiang Rai food. I missed it because of a small deviation in Google Maps, so I came to visit it the next day.
The plain facade is easy to miss. The burgers in the store are made to order. The bread is very soft and large, which is very satisfying, but it is not suitable for Chinese stomachs.
