There are two tribes in the world of tacos. There are the steadfast purists who prefer things simple, who value well-cooked, well-seasoned meat inside a double corn tortilla with some onions for crunch, cilantro for pungency, and perhaps some hot sauce for a little extra heat. And then there are the rest of us, the hungry and curious, who don't mind when taquerías push against the arc of taco evolution, or even think outside the curve. If you're a purist, you should probably move along, but if you're open-minded, Velvet Taco completely obliterates taco convention. Say what you want, but don't argue the ingredients are inferior. Everything tastes fresh and of high quality. Four-fifty may seem like a lot for a taco (cheaper versions start at $2.50) but you get a lot of food for your money.
