Boundary Rooftop
Sir Terence Conran's Boundary became even better with the opening of its rooftop terrace. Dotted with potted herbs and olive trees, there is ample space for drinkers to sip on the English martinis (gin, elderflower and cucumber, £8) and cocktail pitchers (£20). Meanwhile, the grill restaurant does summer eating perfectly: scallop and pancetta brochette (£19), or a whole native lobster (£38). It's open from midday to 9pm, subject to the weather.
