We suggest you make a reservation here before you arrive in Bangkok because of how popular it is, prepare to wait in line if you cannot get one. Thai food cooked with fresh seasonal ingredients in authentic ways, what more could you want?

We would not put it past you if you simply walked by this unseemly restaurant, however, step inside and you will eat some of the best Khai soi (coconut curry noodle soup) of your life. 

Totally unassuming, and therefore even more worth a try. Soei is the most casual of casual and offers traditional meat and fish dishes.

Flavourful beef noodle soup with fresh herbs and lettuce. If you arrive early enough, ask for the Kobe waygu option, which sells out quickly.
