So, I'm just an American tourist who wanted some Poutine and some drinks to end the day. Jack Astor's was very fun - it's at a great location at the corner of Yonge and Dundas and looks into Dundas Square - however, I had to sit inside because all the balcony seating was always taken and always had a long waitlist.
Staff seems a little out of it...very slow at taking requests and forgot a few things a couple times. Very friendly though! Took quite a while to get drinks, but the bar was very busy.
As the night went on, the music got louder, so don't come here if you want to carry on a conversation.
