Check out the Red Barn At the Outlook Golf coarse in South Berwick its only 20-25 min from Portsmouth and worth the ride. It has a nice lodge feel and its a newer place.
Try the Wentworth Golf Club...the White Barn Inn....
I just attended a wedding reception at The Coastal House in Wells. It's obviously not Portsmouth, but it's within half an hour. They did a really great job hosting the rehearsal dinner, cocktail hour, reception and departure brunch.
Wentworth by the Sea is the best food and service in NH by far. Call them!
