Finally had a chance to try out the YYZ Signature Suite, my first visit to a Signature Suite. Weekday early evening, and the buffet area and dining room were busy but not crowded. I sat in the dining room.
I’m impressed. More of a restaurant than a lounge, but wow.
AC has shown they know how to deliver good food and service - they just need to be able to replicate it in air and deliver a consistently good product/service onboard.
