Steam Whistle has a special place in my heart. The first time i ever had their beer was when I decided to visit the Steam whistle brewery.
We had just finished a visit to the CN tower and walked over to the roundhouse for the tour, when we got there we had just missed the tour and the next one was not for an hour. So what did we do, drink Steam whistle! The lovely bartenders just kept giving us samples (and by samples i mean full glasses) of Steam Whistle.
The tour was great, they let you bring your beer around so you don't sober up. It was interesting to learn that they do not use preservatives so the beer doesn't give you that full feeling most beers leave you with.
I really wish they sold SW in the US. This was my 2nd favorite attaction in Toronto after the CN tower.
