Dunkin' in Coronado operates inside the Navy Exchange at Naval Air Station North Island, Building 2017, serving the full espresso, drip coffee, donut, and breakfast sandwich menu exclusively to base-access cardholders in the 92118. The counter shares the NEX complex with McDonald's and other grab-and-go vendors, consolidating quick-service dining for active-duty, dependent, retiree, and DoD civilian populations on the installation. Entry requires a valid military ID and passage through NASNI's main gate on McCain Boulevard at the north end of Coronado Island. The menu covers Dunkin's full beverage platform — iced and hot espresso, cold brew, frozen drinks, Munchkins donut holes, bagels, and breakfast wraps — calibrated to the same national specs as stateside retail locations. Off-base alternatives for single-origin roasts and craft espresso include Trident Coffee Coronado on Orange Avenue, accessible to the general public without base clearance. The location processes Dunkin's full iced and hot extraction program, cold brew steeped on a multi-hour cycle, and warming-oven breakfast builds — the only nationally branded specialty coffee counter on an installation supporting over 23 aviation squadrons and 36,000 military and civilian personnel. Active-duty personnel and families stationed at Naval Air Station North Island on Coronado Island drive or walk from the base gate to reach this location, while mainland visitors cross the Coronado Bridge or ride the Coronado Ferry to the island's dining district.
