Agree, the Octopus Bar is a great place if you're after AFL/ARL games...it's the first bar as you enter Soi Seedragon (on the left hand side)
Phil, Rambo (and Bowy when he's in town) love their sport and they and their girls will surely show you a good time.
It's airconditioned with 6 pool tables upstairs and downstairs (the girls are seriously good at pool) and they play some good music..
They even sell Singha light (3.5%) which is not common in most other bars around. (believe me, it's handy when you plan on being UP all night!)
There's gonna be big crowd there for the AFL finals in late September..and I'm sure Phil will crank up the barbie...
