Quieter Dining
Artist Point: Lovely ambiance, good food, excellent service, superb wine list, and you can walk the beautiful grounds of WL after. Can also see fireworks from Geyser Point with piped in music.
Jiko: Same comments except not as much to walk around and see after dinner and no fireworks. Still, a very good experience.
Convivial Dining
Morimoto: More of an urban vibe than either of the two above. While menu is more diverse (which might help with four people), some of it is just different take on typical Asian foods. Some items are very good, though, such as the buri bop. Fun experience overall.
Boathouse: Good food and very fun atmosphere. Can also sit out on the deck. Lots of choices for various tastes.
Both the two above offer the ability to explore Disney Springs and enjoy more than just the restaurants.
Noisy Dining
CA Grill: Expensive but good food, service, wine list. Obviously, the fireworks are a big draw. However, CA Grill is very loud; hard to carry on conversations. Like the place, but if we go, we do so knowing that it will almost always be above normal noise level for an expensive (and it IS expensive) restaurant.
