I have spent almost 1hour trying to find Metal Quest, as it is now located in a freshly renovated shopping center,
which means, no street address, no signs or whatever.

I was quite disapointed after that "quest" to find myself in a little shop with maybe 30 cds for sale and even less t-shirts.
The good point was the beautiful collection of vinyls. if you are a vinyl collector, that is a good spot
Other than that I wouldnt spend such time to find that place..not worth

If you visit Bangkok you'd better stop at "triple six"

You have to go on a Metal Quest to find this place.

One listing said 3rd floor of Big C. I went only to find a supermarket.

Another listing said 5th floor of Big C and I went there only to find cinemas.

I did ask people in the complex and they had no idea what I was talking about.

Was here in Nov 2007. It's a really cool little shop with a really great, really extensive extreme metal collection. Impressive range of CDs, even more impressive collection of LPs! Owner speaks limited English. BUT NOTE: the address here is wrong. The store is actually on the 5th floor of the Big C Rajdamri shopping mall (opposite Central World; you should be able to find it on any decent Bangkok map).
