If McDonalds was the only place I had to eat I would only eat their fish sandwich and fries... and I hate their fish sandwich. The filet is steamed and fused to the bun. I like Checkers fish sandwich, it is made to order, crispy outside and just right inside, add tomato and onion and it's a joy. Since Sonic dropped their fish sandwich the only other fast food sandwich I would get is Burger King's fish sandwich or BK veggie or a veggie and cheese sub at Subway.
I definitely vote Taco Bell over McD's. There I enjoy bean burritos (add sour cream) or Nachos Bell Grande, minus meat + plenty of mild sauce
I actually love very hot and spicy food, but the seasoning in Taco Bell's mild sauce goes so much better with the stuff I get. Their Fire sauce was great though with the grilled veggie fajita they used to have that had rice in it.
