(people.com ) - Jennifer Aniston had a private meal with musician John Mayer in a Miami restaurant that opened Friday afternoon just for them. "I was happy to accommodate them," says Charles Bell, general manager of Michael's Genuine Food & Drink in the Miami Design District, which opened its doors for the pair early at 3:30 p.m. for the 90-minute meal. Sitting across from each other in a booth, their heads were close together, and they were engaged in a private conversation, says Bell. "I can't speculate on what kind of meeting it was but they looked happy and seemed to have a great time," he says.Aniston, in Miami shooting the movie Marley & Me with Owen Wilson , ordered a chopped chicken salad, while Mayer had a Serrano ham sandwich which "Jen ate some of," says Bell. For dessert, they shared a chocolate-and-peanut-butter layered treat.
