Yay! I'm a fan.
To say the burgers are out of this world is silly. Half the point of coming here is to customize what you want how you want it. While this may be a rip-off for some might be a steal for another. Plus, it's pretty hard to screw up a burger; it's also pretty hard to excel at a burger. Here is no different.
So let's talk about what makes this place great. What you might not get in quantity of burger, you surely make up for it in how much fries you get. The cup is just a formality as there's enough for two or three adults. Is that a part of their business design? Maybe, but at the very least it's a part of their excellent service. They are super courteous and friendly. Best of all, they make it sound like they're having fun. That always leads to a better product. Also I dare any fast burger joint to actually come to my table and ask how I like my food. Well these (Five) guys sure took me up on it.
