This is definitely one of my favourite places to chill in Union Station. The GO concourse downstairs may be hoppin', but the seating area here could be just about dead. The seating area itself is deceptive - it doesn't look huge from the station proper, until you turn the corner. Then... yikes.
The TV is usually tuned to the Jays or Leafs game, which is nice - otherwise, pretty much whatever the staff wants to watch. Getting to watch Mortal Kombat while waiting for the train was very welcome.
Food is, as per Harveys usual, a lot better than the McDonald's downstairs. Having said that, the speed is a good deal slower, and the price a bit higher. Also, Pepsi rather than Coke - not my favourite.
All in all, I can't say I've ever had a problem here. If time allows, it's a nice upgrade from what's available on the GO concourse - and, as I mentioned before, often a lot quieter.
