The beverage business is rapidly changing and drive-thru coffee concepts like Scooters Coffee are right in the middle of it.

This week’s episode of the Restaurant Business podcast A Deeper Dive features Joe Thornton, the president of Scooter’s.

Scooter’s has quietly been one of the fastest growing restaurant chains in the U.S. System sales and unit count have nearly tripled over the past five years, according to RB sister company Technomic.

Thornton talks about that growth and what has been key to the business. He talks about the brand’s franchising model and its focus on its drive-thru coffee kiosks, which sell a selection of beverages and food from 600-square-feet shops.

He talks about the brand’s real estate strategy and where the company fits in a rapidly changing and shifting beverage business.
