But the best place in Thailand for street food is definitely Bangkok.
This picture has been taken in Khao San Road, one of the most lively (probably the most trendy) boroughs of Bangkok.
This is the preparation of a Pad Thaï, a real institution in Thailand.
It is a traditional recipe with pan-fried noodles, various sprout seed, tofu in crumble, yellow beans and grilled shrimps. (which can be replaced by beef or chicken) put in fish sauce named nam pla. It is served altogether with a sweet sauce made of green lemon.
Delicious !
