Not that all Denny's Restaurants aren't fine, but Cordelia's Denny's is by far and away the best.  Why?  The service!  The wait staff is the best anywhere and the owners are generous and caring.  The coffee, I'm told, is excellent, though I prefer my Diet Coke.  Great breakfasts, great sandwiches and burgers.  And even great Senior specials.  And Mani and Mona Trewn - management - are incredibly nice and most generous.  What's not to like?
