What fast food chain has the most locations globally?

Subway is the correct answer because its low-cost, small-footprint franchise model allowed it to open more individual outlets than rivals. Sandwich shops fit easily into malls, gas stations, and street corners, so Subway spread rapidly across thousands of communities worldwide—even if chains like McDonald’s often earn more revenue per store. Remember it this way: “Subs multiply.” Subway’s simple menu and minimal kitchen equipment make it easy for entrepreneurs to launch locations in places where a full kitchen isn’t feasible. That flexibility fueled an enormous global count. Fun fact: while Subway leads in number of restaurants, other giants often lead in sales, showing that store count and total revenue aren’t the same metric.
