What do you want to know? There are usually several specials every evening depending on what fresh fish the chef was able to get so it's hard to say what's the best. I've been so many times that I've had everything on the standard menu so I usually order one of the specials.
The scallop and pork rib appetizer is one of the best courses at any restaurant at WDW, including V&A (where I've dined many times also). However, it's large and very rich (you get two scallops). So if I get this, I usually split it or have it for my entree.
The raw bar is excellent for appetizers. Just make sure to bring plenty of $$ as it's expensive. I always have a few oysters since I don't have much opportunity to get fresh ones. I think they are $3 each here.
Out of the entrees on the regular menu, I enjoy the Cantonese lobster and the swordfish the best. The dancing fish is a spectacular presentation as they filet it tableside.
Bluezoo has an award winning pastry chef so I try to have dessert here (not much of a dessert eater). The best I've had was a special that was a chocolate peanut butter bar. The truffles were very good too.
A real highlight of this restaurant are the drinks. The mixologists here make an assortment of incredible martinis. My favorite is the Serenity. If you like bubble gum flavor, try the Bazooka.
I've read that conventions sometimes make this restaurant busy/noisy but I have never experienced that. The only night that there was any noise was last year when Chef English was hosting a large group of his friends at the table next to us (although he was gracious enough to come to our table and chat with us and take photos). Other than this one time, the atmosphere has always been quiet and very adult.
I can't speak about the non-fish dishes offered because I've never tried them.
I also enjoy Il Mulino but not as much as bluezoo. Part of it is the environment because Il Mulino is not as upscale/quiet. However the food is good, portions are huge. Since you get an amuse bouche, I never get an appetizer, it's just too much. I usually can't finish even half of my entree as it is. The tiramisu is very good so we usually split a piece of it between the table. You also get complimentary lemoncello but I skip it.
