I used to hate Wendy's because the burgers would soak grease through the whole bag, but I definitely fuck with double stacks and their fries a lot when I get fast food these days. Their toppings are always solid, hands down best fast food pickle in my opinion. I like that the double stacks taste mustardy. Their fries are my favorite too, skin on and unapologetically salty.
Jack in the box is only a couple blocks away, and a sourdough jack + egg is my go to there. I usually don't like tomato much on my hamburgers but it just works so well on those.
