20 Upper Ground, Southwark
This botanical bar that crowns the Mondrian's Sea Containers on the Thames is stewarded by mixologist of the moment, Ryan Chetiyawardana. Besides his innovative cocktails—many made with high-tech techniques all his own—the Tom Dixon-designed space is plushly outfitted, and there are unparalleled views of the Thames both on the top floor of the hotel, and downstairs.
