Found yourself in King's Cross? Get yourself to The Standard hotel and seek out its ground floor bar, Double Standard. You'll know you've found it when it feels like you've time-travelled back to the '70s London Underground. Geometric patterns, bold yellow and blue colour scheme, kitsch furnishings. If you're into retro-cool, you'll dig this place.  

Pull up a chair and dip into the experimental cocktail menu. The Pick & Fizz is sweet and bubbly. The Gherkin Martini is crisp and sour. We can never resist a pimped-out Margarita, so we're all over the Don Julio Blanco, Cointreau, lime and ginger foam blend that makes up the Ginger Margarita. Late-night hunger pangs? The food menu keeps rocking until 11pm. It's inspired by traditional pub classics and NYC dive bar food. Their luxe mac ‘n’ cheese topped with black truffle shavings alone is worth making a meal of.
