We drove 7+hrs from NYC to Canada for this, and I'd gladly do it every season.
The food is pretty much the best I've had in my life. Even though the restaurant was stuffed with guests, the waiters went above and beyond for everyone. The maple cocktail was incredible, and went well with the meal.
The meal is definitely fit for a larger group. There's so much food you're pretty much guaranteed to have plenty to take home.
