Like any good food story, the exact historical origins of the taco are shrouded in mystery, and most likely lost to the sands of time.
Of course, if we're talking tacos, or Mexican-American cuisine in general for that matter, it's impossible not to mention Taco Bell.
Taco Bell is undeniably the biggest name in the taco game, but it's certainly not the only player.
California-based taco chain Del Taco is big on the West Coast, but largely unknown to East Coasters and those living in the Midwest.
Taco John's has been in the taco game for a long time. So long, in fact, the brand actually owns the trademark for "Taco Tuesday".
OK, Bubbakoo's might technically specialize in burritos, but their Sweet Chili Shrimp Tacos and General Tso's Crispy Chicken Tacos are delicious too.
If you're not from Texas, there's a good chance you've never heard of Taco Cabana. Besides six locations in New Mexico, the pink-logoed taco brand operates solely in the Lone Star State with just under 150 units.
Earlier this year the taco chain also announced plans for a new franchising program, no doubt with an eye toward expansion.
