I sometimes feel like people at YYZ use a different Plaza Lounge from me. BR and EK use the Amex Lounge in the Int'l area and I've always found it crowded and uncomfortable. The food IMO is worse than in the Int'l MLL and the wine is terrible. When I fly BR I usually stay in the MLL until they close then go over to the PP. I don't often have the hot meals in the MLL, but the soup is usually OK, and I like the new breakfasts.
Having said all that, I agree that the BR Lounges in TPE are excellent, as well as most of the EK ones.
And just to make you jealous, penguin, I'm flying BR tonight!
