Re Taco Bell Taco bell is pretty awful, an I say this mostly because real Mexican food is easily one of the top two or three best cuisines on the planet. The only imitation Mexican food I can handle is Chipotle, because despite being completely different from actual Mexican food, it's still got fresh ingredients and tastes phenomenal for fast food. Of course there are morphologies of Mexican food that have evolved in America such as California burritos (huge burritos with avocado, potatos and steak) which are good as well, but I digress.
Taco Bell as Del Taco are both shit. The cheese on their nachos and burritos doesn't even taste like fake cheese it tastes like fake butter, and the "meat" is like a wet slop of marinated paper clippings.
Real Mexican food - 10/10
Taco Bell - 2/10
Subway is subpar in America and even worse in Japan. In Japan it's even more flavorless and keeps you full for all of 10 fucking minutes. At least you can get them to pile and pile the veggies in the US. In Japan they just tell you "I'm sorry, there's no excuse for this..." and proceed to ignore your requests.
Fuck me I miss In n Out, Chipotle and Submarina. And most of all Mexican food.
