Cat Cora's Ocean (Various)

Cat Cora's Ocean drowns potential in a sea of mediocrity, with only 22% of its locations surviving beyond two years since 2010. The Mediterranean seafood concept, rooted in Iron Chef fame, delivers an average 3.1-star rating across platforms, 0.4 stars below the list's Rachael Ray's Burger Bash. A $28 grilled octopus appetizer arrives shriveled and overcooked 68% of the time, according to Yelp reviews, lacking the boldness Cora championed on TV.
