At the Bishops Finger in the upstairs room. This is just across the square (anti-clockwise) from the previous Butcher's Hook And Cleaver.
It generally starts around 7pm, though some people come earlier.
Please note that many people tend to turn up without putting their names down. This is a bad habit because then other people are discouraged from coming. Don't be either of those types of people.
I'll be there
I can't make it
