I would think your best bets for solid fall hours on the seacoast would be wentworth by the sea or the Cliff House. Chef at the Cliff House is a ski bum who spends a good portion of his winter at Copper Mountain. I don't do business with him currently, but he knows me, so I probably could get an interview for you.
Haha that was on my radar. I actually worked there previously. There season is about perfect and I would feel pretty comfy walking in there mid season. Who is the current chef?
