George Clooney's stag night involved two bottles of tequila and a €320 bottle of red wine.
The 53-year-old actor dined with friends at pricey Da Ivo on Friday night, ahead of his marriage to human rights lawyer, Amal Alamuddin, 36.
The restaurant's staff said George and his six guests drank two bottles of Casamigos, his own-brand tequila, before enjoying a third of a magnum of Sassicaia, a Tuscan red wine which is worth €320 a bottle.
George and his guests ate a dinner of stuffed courgette flowers, pasta with truffles before tucking into figs, crab and lobster.
The restaurant's chef Luciana Gambardella told The Independent on Sunday newspaper: "He's a wonderful person. And [what] moved me the most was how he made a point of going up to every person working in the restaurant to thank them after the meal."
The wedding - which took place at the luxurious Aman Canal Grande resort in Venice, Italy on Saturday - was attended by a whole host of celebrity guests including U2 singer Bono and his wife Ali Hewson, Matt Damon and his wife Luciana, Cindy Crawford and her husband Rande Gerber, Emily Blunt and Bill Murray.
