McDonald’s Corp., the world’s largest burger chain, has consistently outperformed its fast-food peers throughout the recession and its aftermath even though it’s raised prices this year. It’s also working hard to give customers more reasons to visit it instead of rivals like Starbucks or higher-end burger restaurants.

The company is upgrading its restaurants, offering wireless access, expanding the number of locations with 24-hour service, introducing healthier food like oatmeal and smoothies, and selling fancy coffee drinks. It’s also testing changes to improve customer service, such as sending an employee to walk through the drive-thru and punch orders into a hand-held device.

McDonald’s sales keep rising, even with price hike
