Bangkok kohsan street

Try KhaoSan Road, it's loads more fun than kohsan street.

You need to clarify what "party" entails- pouring buckets down till you vomit blood, or standing around with a G & T telling tall tales of all the places you've been to.
Different places for different styles.

Just walk down the street and see what you like.

I personally like Gazebos just around the corner from Gullivers at the Police Station end. There is a less backpacker clientele and more locals. Gazebos features live bands with western songs on a rooftop bar. Later the Hip-Hop rooms opens.

You cant go down KSR for 10ft without stumbling over another bar/ restaurant. Theres also streetside bars down Soi Rambuttri that only open at night.

For someone who spends/ spent so long in the area, you really ought to learn how to spell "Khaosan Rd" correctly

Some of the best food to be found in Bangkok is at Krua Apsorn: http://goo.gl/maps/rKp9

Less than a kilometer from KSR: http://goo.gl/maps/5OGC

Order the crab with yellow curry, a vegetable and some rice. Great stuff!

Closed Sundays.

Considering it's karaoke English there's no 'correct' spelling for it. I spell it as it's pronounced. It's pronounced 'kowsan' by the locals not 'koh san'. It's not an island.

A lot of Thais spell it 'kowsan' or 'kowsarn'.

But, although a typo, and transliterations can get crazy, you spelled it "Kownsan".

A typo indeed. I spelt it as 'Kowsan' two more times in the same post so I think it was evident how I spell it.
