tl;dr: Expensive, not very good, they tend to overcharge you if you don't watch your ticket.
I've had them a few times over last semester to try them out, I've been dying for a really good burger joint on campus. First time I had a burger, fries and a drink. Totaled over $12. I found the burger to be over salted and overdone, but the fries were tasty.
Decided to try them again later in the semester, giving them a second chance. Tried the sliders this time (you know, signature item). Again, they were way over salted and I found the same thing happened to me as a previous reviewer, I was charged 3x $0.75 for the cheese on them and other prices were higher than the menu board (even 3x $0.50 for cheese is a bit high for slider-sized burgers).
Well, in all I'm sad that there still is no good burger joint on campus.
