Reuben dog (from left), chicken-apple dog, tuscan dog, Kenturkey dog and Merquez dog at HD1 in Atlanta. John Kessler writes, "When you order a hot dog, are you the lone-wiggle-of-mustard kind of garnisher or more of a chili-cheese-slaw-Russian-dressing sort? If you're the latter, then prepare to have a blast exploring the menu at HD1, where the dogs come piled to nose-engulfing heights with garnishes you would never have before imagined." Two stars.
