I don't know if no one in Toronto has ever had an actual burrito before... There's nothing very burrito-y about these sandwiches. The food here is pretty damn good, these are great sandwich wraps- these are not burritos, and I'm surprised that they've won best burrito in Toronto because seriously, I have never had a burrito like this. And I have had a fair share of burritos back home in the Pilsen neighborhood of Chicago, deep in the heart of Texas, and honestly, it's one of my favorite foods, i try to pick it up any city I go to, including Berlin, Riyadh, and Beijing (the weirdest burrito ever).
Again, it's a great place to grab a hearty bite, although their salsa comes in those costco-sized jugs (you can tell) and seriously, I'm not sure what the sauce combination is in these things (it's good, but mysterious). It's just not a burrito. It's a really good wrap though. I'd recommend the Steak burrito on wheat, pretty delicious.
Onto the service: They're very quick, and even when the lunch crowd is heading in they're extremely good about keeping the line moving (and have never messed up my order! I've been here a good few times). They staff is courteous and is good about shepherding the crowd without sounding annoyed about it (it's a small store, maybe five stools and one bench to sit on, there's also a picnic bench outside for when the weather's good).
I'd recommend it, pretty highly. I approach this place the way I approach Soy Milk- I don't think of it as milk, but i find it really yummy all the same. They're not serving burritos, but they're serving some pretty darn good tex-mex themed sandwiches. Try it, you won't be sorry :)
Oh! Also, before I forget! To avoid the lineup you can call in your order a few minutes ahead, it's a nice quick option for if you already know what you want (all their ingredients and combos are available on their website, so it's good for first timers too)
