In my opinion, In N Out is the best fast food restaurant serving burgers, ever. Why? It's still fatty foods but has a more healthier process than McDonalds or BK. Employee's are super nice! And their food is affordable for combo meals.
Whenever I have late night cravings for burgers I hit up In N Out and get a cheeseburger combo with a coke, and a strawberry shake. I spend less than $10 including tax here for a combo + a milkshake. Whenever you go through the drive thru I love how they ask if you're eating in your car because they give you a mat and box to make it easier for you. Each time I came into an In N Out restaurant the place would always be clean and even when you watch them make food they look like they carry out proper sanitation procedures.
