Came here recently for Sunday brunch, as it's one of the only places in Toronto that does a nice buffet on the weekend. It also has some nice historical aspects to it. The place is big and a tad confusing - for the record, you can enter the restaurant to the right of the hotel's main door and not walk through the whole hotel in a circle as we did.
Reservations, I assume, are accepted but we did not have one and had no problem being seated. We actually got a nice table close to the buffet. The place has a very old theme to it, even somewhat medieval.
Service was pretty good although sometimes it went from attentive to nowhere to be found. In the end, our female server eventually made her way back to us and I suspect she was very busy.
Food was good! Lots of options from salads to breads to hot items. I feel there were a couple of 'misses' for Sunday brunch that could be incorporated: an omelette station and juice included with the meal. Otherwise, value for quantity/quality is excellent - there are a ton of options.
We would definitely do this again. Or maybe try their Sunday dinner option. Oh and one last side note, we both wore shorts and felt a tad under-dressed. I would recommend wearing somewhat decent clothes for brunch - it appears everyone else does. :)
