The biggest Starbucks in the world is slated to open in November in Chicago — a four-story, 43,000-square-foot caffeine mecca that will employ 200 people.

The Starbucks Reserve Roastery Chicago, a mega store that was first announced more than two years ago, is taking over a space in Chicago’s Magnificent Mile retail district that was formerly occupied by a Crate & Barrel.

In addition to the usual assortment of frappuccinos and matcha green tea lattes, the new super store beginning Nov. 15 will offer on-site roasting of coffee beans, interactive tours, exclusive drinks and a full kitchen for making desserts, breads, salads and pizzas.

Starbucks’ Reserve Roastery shops, which the company calls “theatrical, experiential shrines to coffee passion,” have also been opened in cities including New York, which has a location in the Meatpacking District.

Opened last December on Ninth Avenue, the New York mega store spans three floors and 20,000 square feet.
