Like most signature dining, they do not enforce the dress code. You'll see people in very casual attire and no one says a peep. However, we always like to dress up a bit for a nice dinner. I love the location of the restaurant, being right on the water and meandering through the grounds of the Grand Floridian to get there, makes it feel like a special experience. There are great views from the dining room and the atmosphere tends to be relaxed and quite nice. However, we've never been overly impressed with the food, it's just been OK for us. We also had pretty crummy service the last time we went, so we're not in a rush to go back. Which is unfortunate because I do think the location/atmosphere of the restaurant are one of the best on property. I'm sure we'll give it another try one of these days.
