Not a big fan... Buddha Bar is very predictable.. Well-marketed though because I'm sure it will be very popular : Sign of modernity for Indonesians, and a taste of back home for expats... In spite of that, I have to admit the location of the bar is really nice, in an ancient colonial building, and that the deco is really perfect. But i would just rather go to Buddha Bar in Paris rather than in Jakarta.
Dress well (no shorts, no sandals, no torn jeans, no t-shirt) and take some money with you...
Update June 2009: Buddha Bar Jakarta has been drawing the attention of worldwide media because Buddhists (it seems like there was an invisible hand behind this, but who?) in Jakarta have been protesting over the use of the name "Buddha" next to bar. They won a battle, if not the war, and the management of Buddha Bar Jakarta is now planning to change its name.
Update May 2011: Buddha Bar is now called Bistro Boulevard. There are no references to buddha anymore. I will check the place when I have time soon. In the meantime, you can look at Bistro Boulevard's facebook page here or its website here.
