We love Tiffins!! We've been twice this year and both visits were excellent. The service was great and the food was the best we've had on property.
We ate at California Grill for the first time in May and must of had an off night.. the service was extremely rushed (the first time the waiter came to the table he asked for our drinks and our appetizers without recommending anything) and the entrees were not that great. The Goat Cheese Ravioli and the dessert was really good though.
We were also not that impressed with the Boathouse.. but we did go for lunch and we aren't big seafood eaters so that was probably a factor.
I say definitely give Tiffins a shot. We are going all out on signatures for our honeymoon in April.. Jiko, Flying Fish, Monsieur Paul, Artist Point, Citrico's, Tiffins.. I'm so excited
