Volo is one of the best beer-centric bars in the city. They do things that set them apart from the competition.
This place is not only a craft beer mecca but also doubles as a brewpub. The folks at Volo brew their own beer under the monicker "house ales." In addition to their own concoctions, they also have a large selection of draft beer (over 30 taps). What I like about their selection is that it is almost exclusively Canadian beers with the vast majority of beers on tap being from Ontario, it's always great when bars support local brewers.
Despite much of their draft beer being local I did see some beers that I had not seen before. Volo tends to carry many one-offs from local brewers and on the occassion that I went even had some collablratove beers from local breweries. In addition to the extensive taps list they do have a pretty exotic selection of bottles, however these are a little too pricey for my liking so I tend to steer clear of them.
The owners of Volo are also the brains behind the annual cask days festival, they have a yearly IPA challenge and often have special events such as tap takeovers. They certainly get bonus points for being one of the champions of craft beer in Toronto.
The place itself is pretty intimate, and has a spacious streetside patio. There is no waiter service so one has to go to the bar to get drinks. The place is usually buzzing but the service doesn't seem to suffer, the bartenders are always willing to make suggestions and certainly know their products very well. They have a small uninspired food menu which is ok if you want a snack but you come here to drink not eat.
They are located within walking distance of Wellesley station, very easy to get to by TTC. Overall this is a Toronto gem, and one of the top 3 places for craft beer in the city.
