No one does happy better than Julia Roberts, PEOPLE reports in its latest cover story. And at the Opium Gardens nightclub in Miami Beach last month, the Best Actress Oscar winner (for "Erin Brockovich"), 34, was downright happy -- partying with a buff blond in khakis and a T-shirt until they left together at 5:30 a.m. "They were holding hands, kissing," a witness tells the magazine. As they were over a shared bowl of chicken soup at the Cuban restaurant Puerto Sagua a day or so later. Says waiter Roberto Lazo: "They were very romantic." Right up until her beau left $15 in cash on the table and headed out with Roberts for some afternoon window-shopping, leaving fellow diners to ponder whether a 33-year-old cameraman named Danny Moder might be, finally, The One. "He's cute, very cute, a good guy for her," says one Roberts colleague of the low-profile L.A. native who has quietly but consistently been at her side for the past several months. "I think she can settle down. I think she is ready now, actually. When she finds her true love -- and this looks pretty real to me -- she is going to settle down and want a family."
