1. McDonald’s gets more customers during off-peak hours. Look no further than the strength of its breakfast business relative that of Burger King, says Darren Tristano, executive vice president at restaurant consultancy Technomic. Egg McMuffin is part of the fast-food vocabulary in a way Burger King can’t match. And beverage and snack offerings such as McCafe and wraps have helped increase McDonald’s sales between meals. The dramatic impact from off-peak business explains why chains like Taco Bell (YUM) are entering the battle for morning customers, while others such as Starbucks (SBUX) are seeking more afternoon and evening business.
