When we visited Singapore, there were two hawker stalls that had a Michelin star. We wrote about one of them in another thread:
Cheapest (6 EUR) Michelin-starred meal in the world!
We wanted to try the second one as well, but they had ran out of food by the time we got there.
We also went to the Pavilion rouge, a proper michelin starred restaurant, where we had the taster menu. It was really good and delicious food. High quality ingredients and good flavours. But comparing it to some of the michelin restaurants we went to in Europe, the quality isn't the same.
