Staying at the Dolphin in July 2010. I can remember eating at the Fountain, Fresh Market, and Garden Grove. We liked them all!
Frankly, I think my favorite food was served at the pool bar. We were sitting in the large cabana by the pool on a very quiet day, and the pool bar had good food and excellent service. And, obviously, the setting was beautiful!
I think it's hard to go wrong with any options at Swan and Dolphin.
