Since 1968, the McDonald's Big Mac (which looks better than it actually tastes) has bcome an iconic American sandwich without ever having been very original. The Big Mac was in fact a shameless copy of the Big Boy burger, an innovation of the Bob's Big Boy restaurant chain. Like the Mac, Bob's burger offered up two all-beef patties on a three-layer sesame-seed bun with a single slice of American cheese, lettuce and a "special sauce" (Thousand Island dressing at Big Boy). It was a mouthful. The new BRGR restaurant in Prairie Village pays tribute to both legendary burgers with its Big Mock, a hefty tower of bun and two thick patties. The beef is topped with Swiss cheese, pickles, onion and a "special sauce" that suggests some version of Thousand Island. (It's not just special; it's secret!) It's a rare culinary case of an imitator surpassing the originals.
