Nantucket's famous Christmas Stroll is always the first weekend of December and this year sisters Mandy and Emma, and Paul, the executive chef, want to do something extra special for Mimi's Place, the restaurant they co-own. It will be Emma and Paul's first Christmas together as a couple and Mandy's first holiday as a newly single and divorced mother of two. Although Mandy does have a promising new relationship, she wants to take things very slow.
