I don't think I've ever enjoyed a gin and tonic as much as I do over here.
Philemon is a good loungey-bar to go to with a group of friends or a date while out and about in Old Montreal. In all my experiences here, I've always received friendly and attentive service.
On weekends the place gets pretty packed as the night unfolds, which is to be expected. So be sure to get there at a decent time if you expect to find a free banquet, places at the bar, or on the high chairs. While you're there, take a look around you to notice the quirky fixtures and appliances that accessorize the space.
