This is one of the best spots in the city to grab a drink and quality pub grub in a cozy, welcoming atmosphere. Donna and her staff are extremely knowledgeable about scotch and treat everyone as equals, from experts to novices. And I know because I had my first Islay here. Go ahead and ask your questions, they'll bend over backwards to find what your looking for and educate you in the process. I've always had great experiences learning about new scotches here. Assuming you can get a seat, the back patio in the summertime is also a not so hidden gem. I also enjoy the niche beer list focused on scottish imports like Innis and Gun and Tennents.
Rounding out this bar is the simple but quality food menu. I think I've tried almost everything from the butter chicken to the haggis and I've never been disappointed. The only item that I found closer to average was the burger but the fish & chips was the best I've had in the city. Overall, you can expect good food that's not going to break your wallet. I can't comment on authenticity because I haven't been to Scotland but friends of Scottish decent seem to enjoy the roast beef and bread pudding, Scottish egg, and the haggis even though I understand it's not served in its most traditional form.
My only knock is that the prices of certain scotches that can get quite high so I've had some bills creep up there after some tastings. But that's really a product of the LCBO system more than anything else so I'm not going to hold it against the Caley..
Overall, fantastic place! Please don't change a thing.
