Wait, hold up!!
I never reviewed Serrano?, the go-to place I've been going to for Rotisserie Chicken for decades?
It is simply the best chicken in the Mile-End, giving the Portuguese places a run for their money. Their bird is small but so juicy and more than enough for 2 people.
Get a large scoop of potatoes, ask for a homemade spicy sauce as well as a scoop of chicken drippings, grab a Inca Kola and some bread and have a feast.
It's not the kind of meal you can eat while doing something else, it requires your full attention as the chicken grease will not allow it.
They do have sandwiches for that quick bite though, but i always go for a full or half bird.
There are many picnic parks and benches in the area, the chicken stays warm for about 30 minutes so it's a good option even if you live far.
