Went to the one in Ajax with the wifey after we had done some outlet shopping. I had heard quite a bit about their burger but didn't go in there with any expectations. In my honest and humble opinion, it is without doubt, the best cheese burger that I have ever tasted. It has actually ruined the burger experience for me at other restaurants now because all other burgers taste sub par compared to Five Guys. The only other burger place that I feel was as good was Shake Shack in New York. I think it is the American Cheese that I love so much. I had to give my complements to the manager at the time. I found the staff to be very friendly and the manager was coming around ensuring that everyone was happy with their order. Overall, a very positive experience. Nevertheless, that place is the Bomb Dot Com!
