It was a trip down memory lane for Ireland's biggest and brightest stars.
U2 frontman Bono and The Voice host Kathryn Thomas were among the guest as 1990s restaurant Tosca threw open its doors once more.
The popular eaterie, which was run by Bono's brother Norman Hewson, reopened for one night only on Friday night in Temple Bar's Smock Alley Theatre.
Tosca, originally located on Suffolk Street, was a favourite celebrity haunt back in the day; Guggi and Gavin Friday were regulars and waxed lyrical about the food and ambience.
Tosca quickly became a pit-stop for celebrities and artists. Naomi Campbell, Bruce Springsteen, Bob Dylan and U2 all called in when they were in town.
Last night, the 25 original Tosca staff returned to host the once-off event under the leadership of Norman and chef Aonghus Hanly to raise funds for the Self Help Africa Charity.
The menu was created specially by Hanly, who is now the head chef of fish restaurant Cavistons of Glasthule.
Punters were devastated when Tosca closed its doors in 2000.
At the time, Hewson said he wanted to invest all his energies in his new organic fast food venture, Nude. Sadly, Nude closed in 2010.
But Tosca's reputation lives on and last night proved its pulling power.
The pop-up restaurant attracted Dublin's glitterati and some of Ireland's biggest rock and roll legends.
Bono and Pogues singer Shane MacGowan and his partner writer Victoria Mary Clarke were among the big names in attendance.
