This restaurant is excellent. It was one of the best meals we had last trip. The rare tuna was delicious, and the waitstaff was very attentive to our two children. The portions are large, so if you are small meal eaters, like me and DSis, I would recommend splitting an entree. The restaurant had no problem with this.
We didn't have any trouble making our reservation upon arrival, but the park wasn't that crowded and we ate there for lunch.
