The patio has a great ambiance to it and there's a decent beer list and those are really the best aspects of Mill Street.
They have a huge beer list, but only about 1/3 of the beer on the list is on tap and when you order one they make a recommendation of another beer that wasn't even on the list in the first place - maybe they should update their menu?
I also felt that the service was pretty subpar. When we put our name in with the host she said she would check for a table for us. 10 minutes later and we're still waiting but two other walk-up groups, as large as ours, have been seated. She then looked at us again and asked if we had spoken to someone. To which we replayed, yes you, and she looked baffled.
Also the drinks for two of our group didn't show up and we had to remind the wait staff several times that they never got their drinks - maybe hire more people if your staff is over worked?
With the exception of the poutine trio none of the group through the food was very good. Honestly the poutine trio is the reason I bumped the review up from 2 to 3 stars.
My advise, come for some beers and the patio, order the poutine and leave it at that.
