USA Today has an article on the front page of their "Money" section this morning about some chains that have "hit the big 1-0-0-0." Some excerpts:
Papa Murphy's, the ready-to-bake pizza maker, has reached 1,000 units after 23 years in business.
WingStreet, on the other hand, has reached 1,000 units in just 4 years. Of course, they share locations with Pizza Hut and are owned by Yum Brands.
Panda Express started in 1083 and now has 1,000 restaurants.
Sbarro's, the Italian fast food chain, opened its 1,000th location in Istanbul, Turkey and expects much of its future growth to occur outside the US.
Panera Bread took 25 years to reach 1,000 restaurants this year.
