METHODOLOGY: Data for the 2019 QSR Drive-Thru Performance Study was collected and tabulated by SeeLevel HX. The study included 10 chains and data from 1,503 visits, with the following break-down of visits by chain: Arby’s (165), Burger King (165), Carl’s Jr. (82), Chick-fil-A (183), Dunkin’ (165), Hardee’s (83), KFC (165), McDonald’s (165), Taco Bell (165), and Wendy’s (165). Visits were conducted across the country, across all regions and dayparts. No restaurant location was visited more than once. All data was collected between June 1 and August 1. Daypart analysis was based on the time of day of the visit—breakfast (5–9 a.m.), mid-morning (9–11:30 a.m.), lunch (11:30 a.m. to 1:30 p.m.), late afternoon(1:30–4 p.m.), and dinner (4–7 p.m.). The distribution of visits mirrored revenue by daypart.
