Building off the momentum of its viral “pink drink,” last spring Starbucks struck Instagram gold—or rainbow gold—with its Unicorn Frappuccino. Besides winning social media, the tech-savvy coffeehouse chain is capitalizing on the success of its mobile order and pay with new convenient offerings for guests. Starbucks opened a pickup-only store at the chain’s Seattle headquarters in April and began testing a cashless location in January. For a more experiential dining option, Starbucks plans to open 1,000 Reserve stores, a large, high-end concept with a full bar and Italian baked goods.
