It is difficult to find a good brunch place uptown, but I think I have found the one.
Tucked away on Main St. in Markham is Main's Mansion serving brunch on weekends only from 9am-3pm.
We ordered the eggs benedict and 3 eggs breakfast and although the prices are a bit high (~$13-15 average), the portions are huge! Each of our meals came with a wide selection of fruits including dragonfruit, raspberries, blueberries and watermelons just to name a few. We could barely finish our meal!
Service was excellent and the waitress came by a couple times to see how we were doing.
Overall, I would definitely recommend this place for breakfast and brunch (much better than Cora's!) although I am only giving them 4 star because it is quite pricey.
Added bonus: free wifi!
