I've been to Barrio a couple times now and I have nothing but love for this place. I've taken my all of my friends here, including those out of town visiting from Montreal, and they were all happy with the food and service at Barrio.
First of all, I love that it's on Queen St E. Easily accessible with a quick streetcar ride from the downtown core. It can get quite busy on some days and you'll have to settle for the quieter and less vibrant patio but nevertheless, the food and drinks are worth the visit. If you really wanted a spot in their highly demanded patio, I suggest you visit in the middle of the week where the wait isn't as crazy as it is on the weekend.
In terms of food and drink, I love their burrito bowl!! For such a simple dish, they manage to get all the right flavour combinations in one dish. It's a burrito bowl. It's not meant to be over complicated. It's simply tasty. This is coming from a guy who usually gets quickly bored with burrito bowls. It looks small but absolutely filling!
I love their Sangria here!! For sure, it's kinda pricey. 10$/glass but after a long of day of work, I don't mind. The sangria uses some of the strongest red wines that I've tasted. The mix is most certainly fruity and sweet but doesn't completely dilute the wine.
All in all, this place has done me no wrong! Looking forward for my next visit :)
