The lowly hot dog, although an American staple, often appears as a punchline in jokes about bad food. Luckily, Denver has Biker Jim, a man with a mission to elevate street food to the level of gourmet cuisine. He succeeded. The Southwest buffalo dog is spicy, meaty and topped with cream cheese and caramelized onions. Delicious! Other creative choices include pheasant, duck and elk, as well as the weiner Wellington: a beef dog wrapped in a puff pastry.
