There's something about fast food that just tastes so good. But after reading all about these little secrets...we're not sure fast food is remotely worth it.
"If there's anybody scared about Five Guys, it's fine. There's no freezer. The burgers are made from slabs of raw meat the day of or the day before. Fries are made every day from the potatoes you see stacked up.
All of the toppings are fresh except for mushrooms. They come in sealed bags. But nothing is notoriously gross.
One thing I will say is that ordering a large fry is always a bad idea. The difference between a large fry and a regular fry is surprisingly small (especially when it's busy). Just order two regular fries and you'll get a huge number of fries" Source
