There are some great hamburger chains in the U.S. places whose patties are beefy, juicy and fresh, and are served nestled between halves of a properly airy and toasted bun. But sadly, they are all regional chains Steak 'n Shake in the Midwest, Smashburger in the mountain states, the Counter in Southern California. When will a national burger chain come into being that serves something along these lines? I believe that this is the year. Too much money is being made by these minichains for the big national ones to ignore their success. Last year's stunt burgers and other marketing initiatives are over; now the long climb toward genuine quality control begins. But who will be the ones to pull it off?
