The Flask, HighgateSituated just a stone's throw away from the village's picturesque Pond Square, The Flask has been serving thirsty punters since opening its doors in 1936. What makes the pub the jewel in the North London crown, however - is it's large (and extensively heated) beer garden, the majority of which is covered to protect patrons from the elements. Tables outside can be booked in advance, but be sure to try and nab the corner spots as they're aided by two overhead heaters on both sides of the banquettes. Originally built to afford pub-goers the ability to peer into the infamous Bedlam asylum next door (now the Imperial War Museum), it still provides fantastic views of the city. For those wanting to take a slice of the action home, the venue offers a 'British Mash-Up' hamper (24 bottles from their favourite breweries) to enjoy throughout the week at home.
