I had the "big Mac" which, from my recollection, was way better than the meat version. The fries are even amazing.
I also tried the chicken and waffles that came with vegan butter (that also tasted better than the real thing) and maple syrup*drools*
The only negative is that the stool seats are so damn small and uncomfortable. It can also get packed on weekends, with a 1 hr wait.
