As long as the content is intriguing and captures your attention, I think length is irrelevant. I have read wonderful long and short works here, then again, some not so much.
Depends on where I am visiting. In New Orleans it would be a shrimp or oyster po'boy. In Maine definitely a lobster roll. In Philly I crave a philly cheesesteak. So many places and so many choices and all are fantastic.
