They walked hand in hand over to their table and looked to be genuinely happy and in love,' an eyewitness says. 'They sat in front of the kitchen at the middle table where they could watch all the action with the chefs and seemed to be having a great time.' Of course the couple had plenty to celebrate besides the romantic holiday.
