First, Dunkin' dropped the "Donuts" from its name.

Now, it's adding espresso drinks to its menu. Dunkin' says most of its 9,200 U.S. stores will offer lattes, cappuccinos and other espresso-based hot and cold drinks by the holiday season. It's part of an effort by the Canton, Massachusetts-based chain to increase beverage sales - already 60 percent of its revenue - and compete more directly with Starbucks Corp.

But it has a long way to go.

Starbucks controlled 56 percent of U.S. coffee cafe sales in 2017, while Dunkin's share was 27 percent, according to Technomic, a research company. Dunkin' said earlier this year it was investing $100 million to modernize its U.S. stores. The company now says more than half that total is being used to buy espresso equipment.
