From my neck of the woods near Buffalo, NY, Tim Horton's is by FAR the busiest coffee spot. IMHO, Dunkin's doughnuts are better, but their coffee is average. Tim Horton's coffee is really good and the long drivethru lines and roadside ditches are good indicators of what people drink. Even when there is a Dunkin and Tim Horton's on the same corner intersection, it's easy to see what people like. Sometimes Timmy's drivethru has cars waiting on the road to get in.
