Just checked out of the Hilton Toronto.
Their lounge has recently been renovated. This was my first stay so do not know what it had been like, other then from reading other's posts.

I believe the pool table is no longer there, at least I did not notice it. I think that the area it could have been in, has been turned into a meeting area, long table w/ chairs around it.
I had been upgraded to exec floor, I assume, since I was given access to lounge - 31st floor (from reading other Hilton Toronto threads there was concern that if you were not upgraded or did not pay for the exec floor you would not get access to exec lounge).
In my room there was a full page letter introducing the staff at the exec lounge by name and letting you know their hours of operation and that they were available to help you. I found this very helpful, hours of operation and a general idea of what would be served. As I many times can not remember if this or that exec lounge hours are from 5-8 or 4-7 or what have you. This one was open until 11pm (as is the hotel pool).
The lounge is very nicely decorated, asian influence. The food was good as well. Sushi, spring rolls, hot sausage, cheese / crackers, fruits, veggies and large chocolate chip cookies. Several types of soda were available, they had 3-4 different beers, 5-6 different types of liquor (w/ instructions on how to make a couple different martinis) as well as about 8-10 different types of tea and then coffee. It is an open bar, as stated in their welcome letter.
They had two computers w/ Net access available.
They have a 40-ish inch flat panel tv in the area away from the food.
When you enter they ask for your room # and last name.
I was greeted three times by three different ppl within the first two minutes I was in the lounge. Everyone was very friendly and helpful (asked for directions for the best place to see a slice of Toronto, two employees conferred with each other weighing the pros and cons of a couple different directions - actually seeming interested in me enjoying myself. Queen St. West was the final decision. Good choice! They even asked me to come back when I was finished with the walk and let them know how I liked it).
Great view of either the Lake or of the city, depending on where you sit.
There were probably only 10 people in there at any given time, it could have held twice that comfortably.

If I wasn't trying to maximize my hotel stays I would be staying there again tonight, instead of the HI&S at the airport.
