At taco bell, ever since I was just a little kid, I've always ordered soft tacos with just meat and cheese.
Routine dialogue with the employees goes like this:
"I just need 3 soft tacos with no lettuce."
Of course, taco count varies by hunger level, but it's almost always three.
When either of my parents make tacos however, I usually eat hard tacos with seasoned beef, shredded cheese (doesn't matter what kind of cheese, but usually cheddar), and refried beans.
Chicken soft tacos are awesome too.
