Here is an Advanced Heroquest "Generating the Dungeon" online application. It generates rooms, doors, corridors, monsters, treasures, hazards and so on.
There are different flavours of dungeon some from White Dwarf Magazine (google White Dwarf Advanced Heroquest), and "Dungeons & Dragons: Castle Ravenloft Board Game (2010)" version.
So you can have a Skaven dungeon, Undead, Chaos dungeon. Although you are stuck with what is on the menu. (Sorry, we stopped serving breakfast. We' re on the lunch menu).
