I wasn't impressed with Sonnys burgers at all. Yes, you can load it with you usual ingredients, just the same as Harvey's. The burgers looked like the thawed frozen type. Def not fresh and home made.
I also got the poutine. I enjoyed the gravy, but they don't use cheese curds. The fries were good, and the portion was massive.
The chicken fingers were your usual deep fried fingers that you can get from a box at home, nothing special.
I don't see myself going out of my way to go again. But if I do end up there, I won't complain either.
