We had the special Easter Brunch in March so I'm not sure if it was more elaborate than a 'regular' Sunday, but we found the quality and selection of food excellent, and the set-up was great too. All of the food was in a separate room adjacent to the restaurant (looked like a meeting room) and although that made for a slightly longer walk than if the food was in the restaurant itself, the extra room made it feel uncrowded and we never had to wait in a long line such as we've experienced at other brunches.
