Local Expert Tips for Bangkok Nightlife:
Insanity Nightclub: "Insanity is right near the BTS skytrain Asok station and also an easy walk from the Nana station. Note that the club will pay for your taxi fare here, and if you come before 1am, there is a 50% discount on all bottles of liquor."
Onyx Bangkok: "There is no public transport to RCA, so best to take a taxi here. If coming on a weekend, you might be best to take the MRT subway up to Rama IX station and then taxi from there, as the routes up from central Bangkok will be very crowded on Friday and Saturday nights. Do note that shorts and sandals aren't allowed, and you need to show ID to get in."
Axis & Spin: "Take advantage of the happy hour promotions from 5-8, such as buy one get one free. Check the Continent website for updates."
