Even by Monaco standards, it wasn't your ordinary dinner party for 12 on Friday night – though there was cake and champagne.

To celebrate his 48th birthday, U2 frontman Bono held a small dinner party at Sass' Café in Monaco. On the guest list: Brad Pitt, Monaco's Prince Albert II and The Edge.

"It was really quite a surprise," the café's maitre de tells PEOPLE. "It wasn't organized in advance. We only got called on it that afternoon."

Despite Pitt's presence, Angelina Jolie, who had visited Bono in Eze with her children last Sunday, remained at home.

The sit-down dinner, arranged by Bono's wife Ali Hewson, began with red wine at 10 p.m., according to staff, even before The Edge arrived for the evening. The meal was followed by a champagne toast and strawberry cake lit with candles; a staffer described the party as "tres speciale."

No word on what gifts Bono received – but what do you give a man who has his own rock band and has already been nominated for the Nobel Prize?
