Suki-Yaki, I didn't bother to remember the name of the crap club... but yeah there was no-one there, and when we got downstairs, they told us that they had just closed for a 'private christmas function'... so quite possibly the same place. Arrggh what a waste of money! Luckily one of the staff was really cute and friendly.
Blade Bangkok will be great too! Pity you arent going upto northern Thailand, there are some great unknown to foreigner bars up there, with great sounds etc. Even some of the touristy type bars are good fun. Rasta was one of them, all the staff had dreadlocks and afros, and I think they did tattoos there too... not quite the hip-hop theme you were after... but I enjoyed it.
That exchange rate is good! Sounds like you have a good amount of money behind you, so enjoy and have a great time!
