La Gioconda was a cafe in London's Tin Pan Alley — Denmark Street — where musicians such as David Bowie and Elton John would eat and meet other people in the music business. The premises subsequently became the Barino coffee bar. The name was then revived as the Giaconda Dining Room in 2008 which expanded to the Giaconda Dining Rooms before being renamed La Giaconda and then closing in 2014.
