Of the upscale restaurants on the monorail, nothing compares to V&A for food quality, service and pampering. However, there is no view. There is a harpist who plays and it's very romantic. V&A also has an upgrade for wagyu beef that is the single best piece of meat I have eaten anywhere in the world.
Of the others, Citricos is the most adult and quiet and also has the best food and service of the Disney signatures on the monorail loop. Again, no views. People go here for the food. If watching fireworks is important, you can schedule your meal so that you can walk down to the Narcoosees dock afterwards and watch there with the Narcoosees diners.
The other two have the views but are noisy, especially if you want to dine during the prime fireworks viewing time. Neither restaurant will guarantee you a view and chances are you will have to go outside to watch (dock at Narcoosees or viewing platform at Ca Grill). Of these two, I prefer Ca Grill over Narcoosees by a long shot but neither would be my choice for a quiet romantic dinner. Neither one of them have a "wow" steak dish IMO. If you want great steak, I would suggest you go to Shulas at the Dolphin. That's the best steak on property.
