Oak Brook-based McDonald’s reported strong growth in April same-store sales figures on Monday.  

The world’s biggest hamburger chain reported a 4 percent increase in revenue at company-owned and franchised restaurants in the U.S. 

Results were even better overseas.  Sales of McDonald’s McCafe drinks and breakfast items drove April revenues up 6 percent worldwide. 

The figures are a snapshot of food revenue and don’t include franchise fees and rents that make up part of McDonald’s corporate revenue.

Revenue at stores open at least a year is a key gauge of a restaurant operator’s health because it excludes results from stores opened or closed during the year.
