Rockhard6911, You've got to be kidding! You're in monger heaven. Ebauche's recommendations are tops for English-speaking free lancers. BATS is a whole lot classier and pricier. There are a ton of places in Kota. I like Malioboro a lot, although I've only been there once. Do yourself a favor and spend a night or two with Jakarta After Dark,
http://www.jakartaafterdark.com/. He'll show you some of the hot spots. He seems a little pricey, but assuming you're not an asshole he'll spend the entire evening until the early morning hours showing you around. You'll undoubtedly run across one or more places you'll like and can return to without him. Take a look at internationalsexguide.info too.
