Every year, my daughter takes me to one of our favourite spots: The Doctor's House, in Kleinburg.
The place is huge, though they have many smaller rooms, some dedicated to moms and babies. The buffet is a real feast, fresh, abundant and sooo good. The lobster... Ah! If things did not change, they charge $31.50 for regular brunch and it is well worth it. And after a gorgeous meal, you can walk around Kleinburg, a lovely quaint village.
Again: This is my independant opinion. Yours is welcome!
