Denny's

Denny's menu offers 145+ items, yet 80% share a single beige seasoning profile—salt, sugar, and industrial oil—making it #2 for flavorless volume. Its Grand Slam breakfast uses 30% more preservatives than the average diner meal, per a 2022 lab analysis, and outperforms Applebee's at #1 only by offering margarine-slicked pancakes that avoid microwaving. Worse, a typical Denny's dinner contains 1,200 calories yet 40% fewer nutrients than Chili's at #4, proving bigger menus mean emptier plates; sodium per entrée averages 1,800 milligrams, 20% higher than the industry standard across casual dining. A 2023 survey found 68% of customers find its menu 'bland and greasy,' reinforcing its repackaging of identical ingredients.
