By all rights this place should be overrun with hipsters, but it's not. During the day it's full of businessmen and conference attendees. At night it's a few confused (and delighted) hotel guests and commuters. It closes at 7pm, so this is not your late night spot.
This is a small bar with a few tables is modeled after a club car. It's a sort of downscale gilded age decor, plus trains. Yes, there's a train that runs around the bar.
You'll notice that York Station has the best bartender, ever. Alina is the only bar who's worked here for 20-some years. It's like if your grandma also made a mean martini.
Prices here are a little higher bars in Toronto as a whole, but cheap for downtown (or compared to New York), and much less than The Library downstairs.
If you're hungry, there's soup and sandwiches if the free bar snacks aren't sufficient. You're in a fancy hotel and people order them all the time, so they must be pretty good.
