I've never had a hard shell taco for that reason. It seems far too difficult to eat.
Eating a hard shell taco goes something like this:
1.) First bite is the obligatory low bite, mostly just the meat at the bottom.
2.) Second bite is mostly toppings as another bite of meat at the bottom upsets the integrity of the the taco leaving a mess in your lap.
3.) Third bite? Anyone's guess. Do you want more "just toppings" or more "just meat" because no human mouth ever has been capable of a full, appreciable bite of the whole thing unless their ancestors were boa constrictors.
4.) Either way, the shell has mostly certainly cracked at this point leaving the individual to manage a mess in their hands as they opt to alternating bites of meat and toppings.
Fuck Tacos. "Taco Tuesdays" are a farce and would certainly be coopted by burritos or a nacho salad would there haven been a day of the week starting with "B" or "N." I don't think anyone actually likes tacos; it's just the zeitgeist and "Salad Saturday" sounds like a page from an extreme leftist vegan's propaganda pamphlet.
