aand before you complain... I live in North East London. No recommendations in the Wild West.
CHESHAM ARMS near Hackney Central : amazing beer garden, piano on Sundays, boardgames to entertain yourself with, lovely staff
SEBRIGHTS ARMS near Hoxton/Bethnal Green : very crowded on Fridays and Saturdays, hit or miss gigs downstairs, indoor seating is quite spacious though, and if you're not packed in like sardines it can be quite enjoyable, the playlist is always great
SHACKLEWELL ARMS in Dalston : the smoking area is a quintessential East London experience, I can't reveal much more, it needs to be experienced
THE PRINCE GEORGE in Dalston : quite a nice pool table area if you're into that, quite a good sized outdoor seating area
THE VICTORIA in Dalston : I saw Lennon Gallagher there once, so, that's why it's on my list
SPURSTOWE ARMS in Dalston : when I say intimate lighting I mean you can barely see a thing... I would say a perfect date spot but it's quite a small space so you will be pushing through crowds to get a drink
MIKKELER in Shoreditch and Exmouth Market : both locations are great, Exmouth is a larger space and usually is more popular, I would also recommend going to Exmouth Market on a warm evening for a Parisian experience
THE DOVE in Broadway Market : They have great mulled wine around Christmas time. Great selection of beers on tap. Go on the weekend, when it's a sunny day.
PUB ON THE PARK in London Fields : MASSSIVE beer garden
THE FALTERING FULLBACK in Finsbury Park : deceiving beer garden split across several levels, making it seem very large, but it's still quite cute
AULD SHILLELAGH in Stoke Newington : one word: GUINNESS. The only good pint of Guinness I've had in London. Stokey is terribly connected though, so be prepared to walk from the overground or take a bus.
.... and when in doubt, look on Yard Sale Pizza's website for their pub partners. Order yourself the best pizza in London and have a pint to go with it.
London Pub Etiquette: Stare at someone for the whole night, never make a move, find them on Hinge later, match, never message, see them at another pub and pretend like you don't know who they are. You will be judged if you order wine, do not order a cocktail unless it's very simple to make. If more than one person in your party is ordering a Guinness, let the barperson know so they can pour them at the same time.
Highly recommend: bringing your own snacks as the beer will make you hungry, the kitchen will have closed, the crisps will be overpriced. Buying a pack of cigarettes to heavily breathe in and out in the smoking area and pose as a new wave actrice.
FYI: pubs are not clubs, they're not bars. They serve hearty food when the kitchen is open, and they serve good beer. The bathroom will be filthy, the air will feel sticky and stuffy. Drinks outside won't be allowed after 10-11 pm and it will close the latest around 1-2am. Honestly, why are you out past 2 am as a 20-something year old anyway. The overground and most tube lines shut before then and you probably need to sleep.
Love ya xx
