Serving unlimited hot, buttery breadsticks is one way the Italian-American chain Olive Garden keeps customers coming through the doors. The casual dining chain opened its first restaurant in Orlando in 1982. It now operates 841 locations globally, earning almost $3.75 billion in sales last year.

After years of decline, the chain just reported its best quarterly sales performance in years, with same-store sales rising 6.8%. Known for its affordably priced menu, Olive Garden has been offering its popular never-ending pasta promotions for more than two decades.
