Got a heads up that this place open after popping by Union Station. Figured it would be a good place to situate a small group on a Monday morning while waiting for a colleague to arrive. Seems to be a good option that is a bit closer than Steam Whistle, and you get a good taste of one of the more familiar breweries available from the Toronto area. In a decent location close to Via Rail, Go Transit, TTC, and the Union Pearson Express.
As you towards the Union Pearson Express you a greeted with the Mill St sign on the ramp. From there you can take the stairs to their lounge where you get some seating, a place to hang your coat, an electric fireplace to sit in front of, and lastly the small bar. There is also Free Wifi for patrons new to the country and USB / 120V plugs for getting some productivity. You can also see the status of the UPE on the status screens in the lounge.
Upon being greeted by the menu; they have an option for a Mill St flight with their beers on tap. Grabbed their Tankhouse Ale while seemed to be a good choice for the time. Smooth and had a good little bit of malty flavor. Also grabbed their Nachos which came on a wooden tray with some sweet peppers, nacho cheese, and some jalapenos. Overall the beer is what you would come to expect out of Mill St, and the nachos were okay with a good crisp.
Overall I would say it is a good place to sit out and grab a snack or even a sandwich with a beer. For what they have it is not bad with $5 beers, with the appetizers/food a little pricey. Due to the food cost, I would rate this a 3.5 out of 5.
