Nongkai gave great schedule - I would add to the Patpong section a drink at:
Radio City
73/1-3 Patpong 1, Silom Road
Bangrak, Bangkok 10500
Tel: 02-266 4567
Open time: 6pm-2am
Credit cards accepted.
Music from: 10pm - get there 9:30 am and find a good seat if you plan to sit for a while!
Very good show band backs Elvis and Tom Jones tribute acts as well as doing their own thing. Right at the heart of the Patpong 'love' scene and has Lucifer's disco upstairs, which also enjoys good crowds. A 'must visit' if only to see the Elvis and Tom Jones impersonators!
