I have been a bit reluctant to join in on this topic as I have only eaten at Denny's a handful of times in my life, and rarely eat at chain non-fast food places, as we don't have any major chain casual dining restaurants in the town where I live, the nearest would be a Chili's about 25 miles away. We do have a Pizza Hut, but don't really count it as casual dining. When traveling we will often tend to eat at Cracker Barrel, partly due to the RV parking, though the last couple of years I have had a few negative experiences there, and in one case the food was so bad I walked out without finishing my meal.
Instead of the national chains, we tend to go for the one off places, or smaller regional chains often with only a handful of locations.
Other national chain casual dining places we eat at occasionally (perhaps once or twice per year or less in recent years) that I tend to think positive things about are: Outback, Texas Roadhouse, Logan's (less so in recent years), and Olive Garden. There are also a few that are not commonly found in our region that I have eaten at while traveling, but it has been too many years ago to really comment on, ie Cheesecake Factory, Red Robin, Bob Evans, Perkins
