I have only been here once for brunch. My favourite brunch place is the Swan and that is how I measure other brunches.
My Mum makes the best scrambled eggs EVER and she sets the standard there. The only ones that compare are served at Frank (the AGO) and cost $16!
The Holy Oak is Swaneriffic and the eggs are Mumtastic. The food is a proper mix of honouring the traditional and adding signature twists that make this place special. The potatoes are flavoured with lemon and mint(?) - sounds weird but is very nice. And the scrambled eggs are PERFECT.
My companion had a version of eggs benedict served on grilled halloumi and she liked it so much she returned the next week.
Good coffee is essential to the brunch experience and some of the very best coffee in Toronto is served here.
The only quibble I have is beet salad comes with almost everything and I am not a fan of beets.
