Long John Silver
I've never actually ordered seafood at a Long John Silver's, but I've seen commercials, which is more than enough for me. My rule of thumb is that any restaurant who's food can't even look appetizing for 30 seconds with access to lighting, makeup, props, and smiling actors is not worth attempting.
Pictured here is Long John Silver's, which tastes like what the aforementioned commercial looks like: white-ish gravy with a hint of heavily breaded seafood. Not even cavatappi can save this, though I dread the day when I'll have to try this with Angelhair.
