The Take
McDonald's Filet-O-Fish is 88% slop. The sandwich exists to move fryer oil and ultra-processed components, not deliver fish.
One bite confirms the stack: engineered patty, cheese slice, tartar, and a bun that dissolves into the oil. No real fillet survives the line.
The Verdict
The Filet-O-Fish is pure industrial template with zero redeeming craft. Walk out and find a real fish place instead.
Buy instead: nothing on the fried menu. Slop Score: 88.
