SEATTLE, Wash. (CBSDFW.COM/AP) – Starbucks is expanding its delivery service to more than half a dozen U.S. cities. The goal is to ultimately offer delivery at nearly one-fourth of its company-operated coffee shops.

The company said it is launching the service Tuesday in San Francisco and will expand to some stores in New York, Boston, Washington, Chicago and Los Angeles in coming weeks. It tested the idea in 200 Miami stores last fall.

“We know we have untapped customer demand for Starbucks Delivers in the U.S. and starting today, we’re expanding our best-in-class experience to our customers both in and out of our stores,” Starbucks CEO Roz Brewer said in a statement.

Starbucks says 95 percent of its core menu will be available for order using the Uber Eats mobile app. There will be a $2.49 booking fee.

In December, company executives laid out plans to expand deliveries in the U.S. and China this year.

Executives say delivery works best in dense urban areas where Uber Eats’ delivery fees are lower because of high demand, and customers spend more than they do in stores.

No word on when the delivery service will be available in North Texas.
