The Hamburger Levels Explained:
The story begins at a Level 3 Hamburger, where all you want is a hamburger with cheese, lettuce, tomato and bacon. That is exactly what you get!
Well, then you get a Level 1 Hamburger, which is actually greasy fries! Yuck, nothing you wanted!
So, then out comes a Level 2 Hamburger. It has part of what you want, the beef patty, but no cheese, lettuce or tomato :(
Finally, out comes a Level 4 Hamburger, and you can smell the yumminess! Not ONLY did they bring out the burger cooked perfectly, with lettuce, tomato and bacon, BUT they also bring something above and beyond...a CHOCOLATE MILKSHAKE!
