I've only been to Forbes Mill twice but the experiences were very pleasant. The service was exceptional. As I have matured, I am have learned to lean heavily on seasoned waiters for advice and counsel on wines and entrees. The two gentlemen I had were great to chat with and dialled me in on what I should order based upon what my stomach was craving.
Excellent food preparation and a great wine list. If they had soufflé for dessert, the restaurant would be equal to a Morton's or Flemings.
This is a great place for either a high-end date or a business dinner. I wish they had more booths. But, I'm old-fashioned that way.
On the weekends you definitely need a reservation but during the week I have not found it to be an issue to just walk in.
