A McDonald's at a rest area on 95N in Darien, Connecticut made the news earlier this year with their pricing. Heavy traffic, a captive audience, and a McD policy that allows the franchisees to set their own prices led to this location charging:
$17.59 for a Big Mac Meal
$18.99 for a Double Quarter Pounder with Cheese Meal
18.29 for a 10 piece McNugget Meal
$17.00 for 2 Cheeseburgers
