If you need AC, Absolute Café is another favourite of Jalan Jaksa nightlife, but most of its customers are regulars: English teachers, journalists, etc.. They have a pool table with TV screens showing English Premier League the more often.
Ali's bar is one of the oldest bar in the street, and it is a meeting point for the African community in Jakarta. Pappa Cafe is getting old, and I wouldn't be surprised if it closed soon. Late at night, you'll always find a few people there though.
A few venues are very quiet: Obama's Fan Club bar, with AC and big screen TV, and Joker, a bar with working girls, Indonesian live music and older clients.
There are a few surprising venues near Jalan Jaksa, particularly on Jalan Wahid Hasyim. The most interesting is the Dyna Pub, with a funny interior design. It has air-con and the owner is very friendly but it's not a happening place. On the same street, you have some prostitute/girlie bars, such as Baku Pada, Embassy 21st or Baby Dolls Café which have live Indonesian pop songs from the 70s and 80s. It's an experience, but you'll probably die of boredom after 10 minutes.
