For me, the Disney operated signatures that have provided the best overall dining experiences have been Jiko, Flying Fish, and Artist Point.
Prior to the refurb, I'd also have put Cali Grill on that list but I wasn't quite as impressed on our most recent visit (still a very good restaurant, however).
Next, for me, would be the Grand Floridian sigs (I'm not counting V&A), where I'd give Citricos a slight nod over Narcoossee's (although, as a PP noted, the surf & turf at Narcoossee's is a good use of dining plan credits).
After that would be Yachtsman, then the park and DTD signatures.
All of the above restaurants will have at least one steak item on the menu.
In a nutshell, I'd put Yachtsman behind all of the other resort signatures and ahead of all the park and DTD signatures.
That being said, the filet at Yachtsman is excellent, I just don't think the rest of the dining experience measures up to other resort signatures (particularly as far as restaurant ambiance, food presentation, and menu breadth).
