Conrad Hilton III arrested for domestic battery after his dinner party can't pay $531 restaurant bill Friend indeed? Conrad Hilton, 53, was caught up with police when his dinner party couldn't pay the restaurant bill The grandson of the founder of Hilton Hotels has been arrested in Florida for battering his girlfriend after he and a friend racked up a $531 tab at a steakhouse and then couldn't pay the bill, according to police. Conrad Hilton III, 53, who is also the second-cousin of reality TV socialites Nicky and Paris Hilton, was arrested at the upscale Abe and Louise's restaurant in Boca Raton, Florida, on Saturday night. He was charged with domestic battery after allegedly grabbing his live-in girlfriend and then shoving her in front of officers. Hilton, his girlfriend and their friend Kenneth Brown arrived and requested a 'discreet' table at the restaurant and then couldn't pay for their food and drinks, according to the Palm Beach Post. After a night of eating and drinking at the posh establishment - where filet mignon runs $48 - the tab came to $531.06. Brown told the waiter to charge the tab to 'Mr Moe's account.' Restaurant staff could find no charge account for 'Mr Moe' and Brown had no other way to pay, so the manager phoned officers. Hilton, who described himself to officers as a self-employed philanthropist, said that Brown had invited him to the restaurant to discuss 'prospective business ventures.'
