Madison ★ 4.1
£££City of LondonMon-Sat 12:00-00:00, Sun and bank holidays 12:00-22:00
The One New Change rooftop bar and restaurant runs eye-level with the St Paul's dome, with a modern American menu downstairs and a long terrace bar that is the closest seat to the cathedral.
Tip: Walk straight through the restaurant to the bar terrace, the queue at the front desk is for diners only.
Radio Rooftop ★ 4.1
£££Covent GardenSun-Wed 12:00-00:00, Thu-Sat 12:00-01:30
The 10th-floor terrace at ME London is the central rooftop with the 360-degree West End view, and the gin-and-tonic list and modern Asian plates keep it from being only a view bar.
Tip: Book a window banquette on the north side for the Trafalgar and St Martin's view, the south side gives the river.
Nightjar ★ 4.7
£££ShoreditchTue-Thu 18:00-01:00, Fri-Sat 18:00-02:00, Sun 18:00-00:00
The basement on City Road behind an unmarked door is the standard against which every London speakeasy is measured, with nightly live jazz and a cocktail menu that takes the prohibition era seriously.
Tip: Bookings only, walk-ins are turned away after 19:00. The 22:30 second set is when the band loosens up.
Happiness Forgets ★ 4.8
££HoxtonDaily 17:00 onwards
The Hoxton Square basement run by Alastair Burgess pairs a tight rotating cocktail list with a no-nonsense room policy that has kept it on the World's 50 Best Bars list more or less continuously since 2014.
Tip: Bookings open one week ahead at 12:00 sharp, set a reminder. Walk-ins get the bar if anything.
The Connaught Bar ★ 4.9
££££MayfairMon-Sat 16:00-01:00
Agostino Perrone's bar inside the Connaught in Mayfair has won World's Best Bar more than once and runs the table-side martini trolley service that the rest of the industry copies.
Tip: Order the martini trolley, the choice of vermouth and bitters at the table is the experience. Reservations open one month ahead.
Lyaness ★ 4.7
£££South BankMon-Thu 17:00-00:00, Fri 16:00-01:00, Sat 13:00-01:00, Sun 13:00-00:00
Ryan Chetiyawardana's ingredient-led bar at Sea Containers is built around the seven Pinnacle Guide ingredients that change every year, and the menu reads like a chef's tasting more than a drinks list.
Tip: Sit at the bar, the conversation with the bartenders is the menu's commentary track. Saturday afternoons are the quietest slot.
