Truly exceptional in every way. I've been a couple of times over the years. I understand that you now need to reserve roughly 6 months in advance to get a table. It's only open on weekends as I recall, and you dine in what is - the rest of the week - their living room. Quiet rustic and pretty in a farmhouse kinda way (be prepared to meet the kids and pets). No liquor license, you bring your own with you. It's a hell of a drive from Toronto, and you wil be drinking and eating for quite some time, so plan on spending the night nearby or having a driver take you there and back.
The food changes each night and is all made using ingrediants from the farm, so it varies by season as well. they will let you know several days in advance what is on the menu for that evening. There is NO choice in the matter by the diners.
Flat rate for dinner, whihc the last time I was there was $140 per person is memory serves.
Hope this helps.
