States with the most dining rooms open, like Texas and Tennessee, had some of the highest sales. Some fast food restaurants which already relied more heavily on drive-thru and takeout have been slow to reopen dining rooms. The company distributed a 59-page rule book that franchisees must follow as they reopen dining rooms. Restaurant Brands CEO Jose Cil says opening dining rooms helps customers feel more confident as they slowly re-establish their routines. NPD analyst David Portalatin says full-service restaurants have more issues than fast food restaurants when it comes to reopening dining rooms.
