We wandered into Steam Whistle on the first leg of our beer tour around Toronto and weren't disappointed! The building is beautifully done inside and out (they do events, FYI) and has plenty of space.
We took a beer tour and got the glass/beer set to go along with it. While we waited we tried their filtered and unfiltered pilsner and had a pretzel snack which was tasty. We learned about the process and beer making, plenty of talk on how environmentally friendly their business operations are- BONUS! There is so much fun and charm with this company and we loved having another beer for our tour.
This isn't what I would call a craft beer place like you may be used to, but their pilsner is a solid choice and you can tell they want to do one thing well. Nothing wrong with that!
