Sales at Burger King's North American restaurants have started growing for the first time in more than two years, sparking hope that the brand's makeover is starting to pay off.
The Miami-based fast-food chain on Wednesday reported first-quarter earnings that included same-store sales growth of 4.2 percent for North American restaurants.
Burger King Chief Financial Officer Daniel Schwartz credited the improvement to strong sales of its new original chicken sandwich and French fries, plus promotional programs. The company also has been cutting costs through restructuring and refinancing its debt.
