Khao san road and soi rambuttri are two small streets in a city of about fifteen million. Go exploring! See things that are in no travel guide.
Where in a travel guide are you going to be able to find an alleyway like this? Here people where walking, and riding motorbikes and bicycles.
But where else are you going to be able to buy an iced chai latte made in true Thai style, by a woman who looked like she had more experience than anyone.
And both of these two places are less than a few minutes away from the Burger King side of Khao san road.
