"The main reason to visit a Denny's is its late-night hours. Ideally, it should be open all night. The food is consistent, whether you're in New York, Florida, Nebraska, or California, but it doesn’t stand out. The service is average at best. The biggest advantage Denny's has is being available when hunger strikes at 3 AM. I recently went there late at night, and while the food was decent and I left a generous tip, it didn't impress me. I've been there plenty of times, only to find a padlocked door despite the 24-hour sign, which has left me frustrated. I’d give it two out of five stars because it’s only open about two out of every five nights. If it were consistently open every night, I’d rate it five stars."
