I still firstly consult the print edition of Spartacus when considering anywhere new and then follow its info up on the www.

The good thing about Spartacus listings is the capital R for Rent in the bar descriptions - so you don't waste time leering over unavailable eye candy.

Having said that, it certainly used to (and still may be) the case that NONE of the gay bars in Thailand were annotated R - which is clearly somewhat ridiculous but I've found the information reliable all over the rest of the world.

The snag is its an expensive book to renew each year but you can always pick up last years edition on eBay at a good discount.
