You may be looking for one of a number of things called "Inferno".

Inferno was a popular nightclub located in London.

In 1966 the club's proprietor was a woman called Kitty. She introduced Dodo Chaplet and Polly to Ben Jackson. Ben then went on to attack a patron who was harrasing Polly.

Shortly afterwards, it was briefly visited by the First Doctor. (DW: The War Machines).
