There are at least two famous kway chap (rice roll noodle) shops in Yaowarat (Bangkok's Chinatown) both on the same main street. There's Kuey Chap Aun Pochana and Nai Ek Roll Noodles. I blogged about Kuey Chap Aun Pochana in 2015 because it left a deeper impression (it later won the Michelin Bib Gourmand award). Nai Ek Roll Noodles on the other hand is no sloth either, it won the Michelin Plate (which is like an honourable mention). In Michelin speak, awards go from Star ⭐ through Bib Gourmand 👶 to Plate 🍽 in descending order.
(Disclaimer: I don't refer to Michelin guides for my food adventures. I don't mind that my food trips are sometimes misadventures as hit or miss, I feel it is all part of the fun.)
