One of my favorite places in Toronto. It a place that I have to bring people when they come to visit. Both the Beer Hall and Brew Pub have great food its just a matter of do you want bar food or "fancier" food choices. The brew tour is awesome. The tour guide was really knowledgeable about the history of Mill St and the whole brewing process. The brew tour was $10, you sign up at the souvenir shop. Included in the price of the tour is a 6oz beer flight (6oz of 4 different beers) and a sample of one of their 3 beerschnapps, which I thought smelled and tasted like tequila, and it went down like tequila too. Service is decent, but there's always room for improvement. The middle-aged female manager was great and gave us the whole scoop about Toronto Beer Week (Sept 13-21, 2013) and gave us the "Passport" booklet so that we knew all the businesses that were participating and where they were located with a brief description of each place too. The booklet even broke them up into chapters and each chapter was a different part of the city. So say you're in the Downtown Core, there's a chapter for that.
Bottom line, definitely worth going to this place and trying some new beers, getting a bite to eat and going on a tour, given every half hour. And if you're walking around Mill Street on the weekends you may even run into a lucky couple that is having their wedding pictures taken among the beautiful brick.
