Discovery Club Chiang Mai
This nightclub is popular every night of the week though typically weekends are always packed and if you go too late you won't get a seat anywhere. One thing about this club is they usually have a band playing,
it's always a Thai rock or pop style band but never very good, especially if you don't understand the Thai it's not that fun. But when the band stops they play English music that is sure to put a smile on your face.
This place is packed with chicks, the smaller bar outside chiang mai bar is a favourite for tom and dee lesbians to congregate. You'll have much more fun at the Discovery night club if you take a group of friends, preferably single Thai girls (whom your "just friends") with. I find that you can easily pick up girls here if you take someone who is going to open you into a conversation.
Dress up and make sure you look good at this place as well, there is no cover charge for foreigners either. Always a plus, and again, why this place is so good, because there are always more girls than guys at this club. If you can't pick up at Thai night clubs, try this place it's always a sure thing. Be careful though because a lot of 15y/o's enter this place and you could get into trouble if you go with underage girls in thailand. Don't bother going to this Chiang Mai nightclub unless it's after midnight because that's when everyone starts rocking up.
