What’s not to love about the OXO Tower Bar at Harvey Nichols’ towering success on the river? Here you’ll find plausible cocktails, beef kimchi sliders, vegetable dim sum with ponzu, and grilled squid with a chilli rouille (£8.50). But the clincher is the postcard-perfect panorama of tourist London (including St Paul’s), seen across the water from the eighth-floor vantage point. Tables can be booked, with seating on curvaceous cream armchairs, but some places are saved for walk-ins until capacity is reached. The drawbacks? Well, 11pm on weekdays and midnight at weekends are ridiculously early closing times. We want to enjoy cherry Manhattans like they do in Manhattan, at an hour when others are fast asleep; and to have the option of ordering Dusk ’til Dawn (Ilegal mezcal, Cocchi, Punt e Mes vermouth and Lagavulin 16 whisky) from dusk to dawn.
