Possibly my favorite spot in town for a drink. A amazing experience from start to finish: what's not to love about the retro turn of the 20th Brit-Canadian aesthetic? Come for the drinks: a full stock bar where each cocktail comes in the right glass and with the right ice. Pick from the diversified options on the menu but don't be shy to ask for something custom: the bar is fully stocked with a variety of options and the barkeeps knowledgable and skilled. The food is equally good (fries that will make you wish they had a poutine) but somewhat old fashioned in it's menu (which is the point). You won't go wrong with the mussels or the pulled pork sandwich, but if you're on the picky side I'd visit fist for drinks before committing to a meal there.
Tavern isn't cheap, but is money well spent every time.
Useful: Busy often. You'll seldom have trouble walking in to find a seat at the bar open for you and a guest, but if you'd like a table call in advance. You don't have to call weeks ahead or anything, but better safe than sorry.
