Always got breakfast at the restaurant in Canadian Delta hotels (Thunder Bay, Fredericton, Sherbrooke, and a few years ago Quebec). This was actually very decent Platinum breakfast offering.
The "Pantry breakfast" is absolutely disappointing and is probably against T&C... Could they go away with it, we should see, in which case I will absolutely avoid this hotel (and chose either the Pur or the downtown Marriott, or a non-Marriott option)
