i tried the mr big stuff burger and found it to be fantastic. the portion is humongous and the quality is great. the beef patty was very juicy and the bacon was quite nice. it was also quite cheesy without being overpowering!
at $16.50 it was definitely very reasonable for the portion you get. however, i'm not sure if i would wait for almost an hour for it again! either that or i'll make sure to plan my time well to accommodate fergburger waiting times!
