Tucked between Highgate Cemetery and Hampstead Heath, The Flask is said to host not one but two ghosts: the first, a Spanish barmaid who broken-heartedly hung herself in the cellar, and the second, a gentleman in a Cavalier uniform who's been spotted strolling through the main bar. Rumour has it one of the first-ever autopsies was (very illegally) performed in the pub's committee room as well, supposedly on a body pulled from a nearby grave.
Despite its grisly history, The Flask has a vibrant energy and surprisingly cheerful vibe filled with natural light and English charm. On a scale of one to five skulls (five marking the ultimate spookiness, of course), I'd give this pub a mere one and a half.
The Flask, 77 Highgate West Hill, Highgate, London, N6 6BU
