If you want to blow a visitor’s socks off, the spectacular views from this strategically located drinking spot are London picture postcard perfection. Heated and canopied, the all-weather bar atop chef Tom Aitkens’ riverside deli is where to ogle icons such as Tower Bridge and World War II battleship HMS Belfast. Drinks to sink include Lifeboat Sidecar (a blackberry and vanilla-infused twist on the classic Cognac cocktail) and Four Roses bourbon, maple syrup and Curious Brew stout shout, The Kraken (£9.50). Otherwise, order accessibly priced southern France merlot and sauvignon blanc; Italian, French and English bubbles - all available by the glass - Kentish craft beers and Breton cider with jumbo corn cobs, salted savouries, cheese or charcuterie boards and seafood platter (£26.50) to share. Open from noon until late from March until late October, expect Tom’s deck to be more packed than a cross-channel ferry on a Friday in July when the sun shines bright. And when it’s January in June? “Hot chocolate all round!”
