My wife and I think it is a hidden gem. It is (by far), our favorite "cool off and relax" lunch spot when we are at Epcot or the Studios. I have NEVER seen it crowded at lunch, and very rarely at dinner. The atmosphere mirrors the Yacht/Beach Club in general: quiet, understated elegance. The food (lunch and dinner) is consistently good to excellent, too...neither of us have ever been disappointed in our 10+ meals there (tied with Kona Cafe as our most-visited WDW restaurant).
For a day when you will be at Epcot or the Studios, go for it!
PS- I have loads of photos, but none are currently accessible online. Maybe I'll upload a couple of them.
