Master Richard
Although I have not read every single review regarding the dungeon. Everyone I have seen is positive and underlines my views.

Both the venue and the keeper are first class and I can't fault.

Although I have my own large dungeon, when in London, I will revisit this one as many times as possible because it is so good. Well worth the cost.

Just double the time you think you want as it will fly and you will wonder where it has gone, while you are wrapped up in this unique palace.
