Many many more cafe and resto arranges F1 Party for the fans. Imagine an open air stage and the band performing their songs there. So close with the spectators and I was singing "Please, please tell me now, is there's something I should know?" [aaawww, back to 1980's Duran Duran ;)]
Dress Code: Casual and F1 theme for sure!
The most happening nightlife district of KL is the area within the Golden Triangle (i.e. Jalan Bukit Bintang, Jalan Sultan Ismail, Jalan Raja Chulan) and its vicinity including Jalan Ampang.
Most things to see or do that one usually looks for in nightlife for KL can be found here. From clubs to pubs, live music to wining and dining, people watching to even a mini red light area can be found most 'happening' around the golden triangle of KL. You can find popular haunts that locals and foreigners alike go for, such as the Hard Rock Cafe KL, Planet Hollywood, Emporium Grand Cafe, Barfly, 12 SI, Thai bars, Irish pubs, jazz clubs, executive night clubs (with hostesses), upmarket or mid-range restaurants (even fast-food or open-air hawker stalls) with local and international fare, cafes (Starbucks, Coffee Bean), etc.
For ladies, ladies' nite are usually on Wednesday and Thursday nights at the nightspots (& they usually indicate if they have one) where ladies gets free drinks and entry all night but guys have to pay! Guys usually looks out for the ladies on these nights though ;-)
Generally, most of the time at most nightspots, they usually run some form of drinks promotion that gives a better deal - please do ask the waiter/bar staff before you place any order if they're running any drinks promotion as it can give significant cost savings especially if you're planning to drink a lot that night. If you had to pay for cover charge upon entry to any clubs or bars (for bars, especially if they have a live performance lined up), it usually comes with 1 or 2 selected free drinks - it's best that you check when you're paying.
Lots and lots and lots of pubs, restaurtants, outdoor cafes and the like up in the golden triangle. One just need to walk out side their hotel and follow the music.
