Used for a long time now by the Extreme Tuesday Club and lately by the Rails/Django meetups.

From the website:

"It may be a bit of a cheek to include this as a traditional pub, as it has only been one since 1995.
This impressive Grade I listed building was erected in 1888 as the Law Courts Branch of the Bank of England. It was designed in the Italianate style, popular at the time.
Ironically an historic pub, the Cock, was moved across Fleet Street to make way for the new bank.
The interior is solid and sturdy, just what you'd expect of a bank. Fuller's Brewery has spent a small fortune restoring and decorating this fine building, and has commissioned new paintings and murals."

"Large columns rise up to the high ornate plaster ceiling. From this hangs three very large brass chandeliers.
The central bar structure almost reaches the ceiling and is so tall, a ladder has been provided to reach the top shelf. Gold and black curtains frame the huge windows and paint effect decorate the walls. The overall feel is rich and opulent. For a good view there is a gallery with limited seating. This is a very popular pub and is often packed at lunchtimes and early evenings. Bar food is available and there is a restaurant through the door marked 'Club Room'."
