Play ran late as Better Bankside's own team 'Better Bouleside' and Globe Business Publishing battled out a friendly Boules final watched by commuters in Borough High High Street.
The four-day Better Bankside Boules Tournament in the courtyard of La Cave Restaurant & Wine Bar behind Southwark Cathedral drew teams from businesses around Bankside.
In the gathering dusk the exuberant crowd cheered on both sides and at the conclusion toasted each team, La Cave and Southwark Cathedral.
Better Bankside's chief executive Peter Williams congratulated the winners from Winchester Walk-based Globe Business Publishing and presided at the presentation of French wine and a set of new silver boules.
The winning team has promised to join in next year's Shrove Tuesday pancake race as well as the second Better Bankside Boules Tournament.
Businesses fielding teams and spectators included Globe Business Publishing, The Team, Ofcom, Southwark Council's Cycling Team, Health & Safety Executive, Very Studio, the London Marathon and Tsuru.
