The good news is that eating street food has many benefits to you as a traveller – it’s generally safe (you can see what’s being cooked and it’s fresh), you get to interact with the locals, it’s authentic, delicious and the best way to give back to the local economy.
OMG, if you love authentic Thai street food you will love visiting Chinatown in Bangkok. There are hundreds of street stalls, markets, carts and restaurants. Night time is when Yaowarat, as Chinatown is also known as, will rock your taste buds.
If you want the really great Bangkok street food, then walk to the end of Khao San Road, turn right past the police station opposite the Wat and Soi Rambuttri and lining the streets will be many many street stalls and carts.
