The quality of the ingredients is great and the burgers themselves are a great treat and that's what it is: a treat!
The only problem I have is that the portions can be a bit too much for me and I end up not being able to even finish a cheese burger with little fries and just throwing them in the waste bin.
I suggest going with a few friends and share the fries around, but other than the overly huge portions the food is worth the cost.
