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), here I have the "Dungeons & Dragons: Castle Ravenloft Board Game (2010)" version in the picture:
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).
Hidden treasure is a bit of a giveaway, so you would really declare a policy of searching or not.
