I went to visit the bar last august and indeed it looked ok.
The place, even if small,is a rock place but not everyday of the week.
It seems that Fridays and Saturdays are the best days for Hard/Metal...
Other days Drum & Bass stuff, DJ crap, DO NOT LISTEN to the people (the DJ's themselves) who are handing flyers in teh street. For them everything is rock and they only want you to enter the place.

But it worths having a look / a drink and ask when the next concert is. Ask the guy behind the bar (not sure he's the boss) but he gave me the right info.

Next time I WILL return and attend some metal live stuff !!!
Cheers Manu.

Was here in Oct 2007, and was very disappointed. The place seems like it should be cool - its a small-ish bar with a little stage, and the whole decor is totally metal, with Sepultura and Soulfly posters, and metal band stickers everywhere. But the DJs don't seem to ever play metal! Instead they play hip hop and (occasionally) radio rock to appease the fratboy scene on Khaosan Road. Very lame.
