As of my latest update, Chipotle operates around 2,700 locations worldwide. Let's assume each restaurant serves an average of 300 customers daily. With an average bill of roughly $10, each location generates about $3,000 in sales each day. If each restaurant is open 360 days a year, the annual revenue per store would be $3,000 multiplied by 360, resulting in $1,080,000. Therefore, Chipotle's total global sales revenue is roughly $1,080,000 multiplied by 2,700 stores, amounting to approximately $2.9 billion.
