Looking for a guide to dungeons, their layout, descriptions etc. Anyone knows if there is a site with this info.

If you mean the generic, non-quest-related dungeons, then the answer is no. Not even the strategy book has any, because the opponents you face, the traps they set, and the treasure they provide vary according to your level.

A guide to quests, including their dungeons, is here on GameBanshee.

And even if there was even just a layout of each dungeon in the game, it'd be useless as most every dungeon in the game has at most 2 different directions that lead somewhere different.
