While green chile may rule in Denver, the Tex-Mex chili reigns supreme at Sam's #3, a local chain of diners with a pages-long menu of Greek, American and Mexican staples. The origins of Sam's date back almost a century, and while the original closed over fifty years ago, the Armatas family opened another downtown eatery on the same block in 2003, with additional outposts in Aurora and Glendale. All of them serve the Tex-Mex chili, a combo of Sam's pork green chile and its red, Coney-style chili, ladled in a cup or bowl over pinto beans, topped with cheese and diced onions, and served with a large, warm flour tortilla. Though green chile purists may bemoan this move, one bite and you'll understand the crossover appeal.
