Just over a week after the stars flocked
to Café Habana for a Caliche rum-hosted fête, David Beckham
cruised on over to the Malibu, Calif., hotspot with a pal.
Pulling up in his custom-made Harley Davidson motorcycle, Beckham was "casually dressed in jeans," an onlooker tells PEOPLE. "David and his friend had a casual lunch, eating chips with salsa and guacamole, and topping it off with beers."
Appearing relaxed during the sunny summer day, the source says, "They seemed to be in great spirits and were friendly to the restaurant staff." – Jennifer Garcia
