Shell. Like crabs and things ........
Excellent.... my wife and I tend to be in the same "boat"

. In this case? Flying Fish is a looser - very little SHELLfish.
The bad news: Everyone ELSE is very much a looser

. FULTON'S used to excel at shellfish - but it no longer exists. Reviews of their actual offerings are few, and suspect.
Boathouse will starve you. Yes, they DO have some food - just not all that much of it. Your choice.
What is left? And PROVEN. The names may surprise you....
Il Mulino (Swan) has several STUNNING shell fish offerings.... Mussles, Cockle's, alive a live oh.... Frutti di mare to die for.
Shula's (Dolphin) has a Lobster offering that could eat YOU. It's huge, and it's VERY good. This is not your daddy's
DDP Lobster.
All personal opinion - I'm not necessarily right, no one else is necessarily wrong. We go to WDW twice per year: 2007 through 2017.
