For Bucknaway ... the drink prices in Patong GoGo bars have always been less expensive than Bangkok.
Last time I was in a GoGo Bar in Bangkok, and then a week later in Patong, it was was standard 200 Baht former, 100 baht latter.

We're not much into GoGos anyway so this was 2 years ago. Now it seems the prices in the more popular Bangkok bars are around 250 baht, so perhaps Patong has gone up as well (to 150 Baht?).

Maybe jinks, who was in Patong recently can let us know.

Cheers ...
