If you want to enjoy the local and nightlife of Bangkok i must say Khao San is must place to visit. When i visit there it was an amazing experience for me to saw the food which where sold out there. I never thought of a crocodile, scorpions, insects is also a food for us but khao san changed my thinking. Not only for this this place is also for party animals. I was shocked by seeing the local beer price 150 THB for a bucket of beer after that buy one get one offer on bucket was amazing. You can also do purchasing but i recommend you not do shopping here because MBK center is much cheaper than this. This place opens after sunset till midnight.
