That's right. The taco chain is half-a-century old. On March 21, 1962, Glen Bell Jr. opened his first Taco Bell in Downey, California, and our nation's late-night love affair with processed Meximerican cuisine (and FourthMeal) began. A new biography of Bell titled Taco USA makes some pretty bold claims about the chain's role in indoctrinating America into Mexican cuisine, and even goes so far as to say, "Taco Bell and its spawn became a gateway for Americans to accept Mexicans." We admit that as much as we might poke fun at the place and wonder a bit about their beef, we will admit to having devoured a Seven-Layer Burrito or two over the years, both drunk and sober, though mostly drunk.
