I remember our 10th anniversary fondly. We had a week at the Yacht Club, second honeymoon, no kids. Dinner on our anniversary was at Chefs de France. Not one person had mentioned or done anything special for our anniversary until we got to Chefs. They seated us on the patio, we had it to ourselves, they sang to us in french, brought us a wonderful dessert with candles on it. It was very nice and romantic.
There are lots of places you could go...Le Bistro, Jiko, Flying Fish, Artist Point,
CA Grill, Blue Zoo, IL Mulino, Italian restuarant in EPCOT (name escapes me right now)
