Jennifer Aniston & John Mayer Dating?

"I was happy to accommodate them," says Charles Bell, general manager of Michael's Genuine Food & Drink in the Miami Design District.

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.

Later, the two were seen at Casa Tua on South Beach.

Mayer, 30, and Aniston, 39, left the restaurant at 1 a.m. When they returned to her hotel, they were observed holding hands.
