Hi dude. I visited Vietnam 4 months ago i had a good time especially going to bars in Hanoi Club 68 is great, it's basically where strippers are put out to pasture to die, the cover is cheap, the beers are cheap, and the girls are... GREAT!
I love this place, If you're not into the high society rich glamour clubs, and just want a low key place to have a drink and meet some really great down to earth women this is the place for you!
