At this Northwest Side favorite, everything includes sauerkraut. Calm down, encased-meat-purity police. It's not ketchup, and it actually blends in quite well. Though that's not what sets Jeff's apart. As regulars here can attest, every hot dog they've ever eaten here has been exactly the same. The perfectly steamed poppy seed bun and extra-snappy natural casing Vienna Beef frank are loaded with just the right amount of garden-style toppings, giving you a consistency that many of the better-known spots fail to match.
