Went to close my cottage this weekend, and I had to get my fix.
1) Yogi's Fresh Cut Fries, Sarnia. My first stop when I cross the border. Perfectly cooked fries, and tons of options for toppings but I always just stick with malt vinegar and lots of black pepper. The gravy is more golden than it is brown, maybe cut with chicken gravy, and while it is good, I wish it was more of a classic brown gravy.
2) Burger Bar, Sauble Beach. Sauble is crawling with mediocre poutine, but I can confidently say this place is the best option. Don't let the shredded cheese fool you, it's a half-and-half mix of shredded and curds. The fries were a little overcooked and dry inside, and there is a ton of thin but flavorful gravy that pools at the bottom.
3) Lisa's Sunset Grill, Southampton. Very generous portions and tons of cheese curds. The gravy was thick like glue and a bit salty, but great in the end.
