we ate there 2 years ago while staying at Saratoga Springs. IIRC, we had the crabcake appetizer, which had 3 different dipping sauces and were small but good. I had the pasta dish that is still on their current menu (described as Penne Pasta with Shrimp - artichokes, spinach, sun-dried tomatoes, olives, and garlic), with no shrimp, and DH had I think, the 1/2 roasted chicken w/yummy au gratin potatoes. I also remember he ordered a drink that was on their drink menu (which is probably gone now b/c of the standardization of all bar menus across WDW, don't get me started), and he couldn't drink it b/c there was something really really wrong with it (bad taste) but I can't remember what it was or why it was so bad!
I do recall that they sat almost everyone in the one room there, so it was kind of crowded, even though there was more empty space not being utilized. The last time we had lunch at Olivia's at Old Key West, the same thing occurred.
It was fine, what we were expecting, but I wouldn't run back there. The menu is too limited. We may wind up grabbing a bite there at some point this year since we are staying at SSR again.
