A stunning lounge, and they accept Priority Pass here. (I think their actual Mastercard holders have a special section reserved for them.)
If you think daytime is pretty, wait until you see this place at night.
Strong wifi.
Plenty of seating and charging stations.
Food is nothing to write home about, but it's a few hot and cold options.
The location that Priority Pass has this lounge listed is incorrect in the app; if you can't find it, it's located just a skip down the other direction from Air Canada's Maple Lounge.
