Is it their Famous Complete Meal?
Train cars *inside* the restaurant?
The location and riverfront views?

I found a note from the history section on the OSF website, relating to the South Waterfront real estate perspective:
"Dussin pioneered the concept of developing restaurant properties in places others considered unworkable. These diamond-in-the-rough locations often are unique and distinctive—even historic—buildings in older warehouse districts where rents are low. As the restaurant's popularity grows, the area begins to improve. Other stores and businesses move in, bringing more people to the area. The Old Spaghetti Factory's traffic goes up, but the rents stay low."
This is true of the Spokane, WA restaurant as well, the only other location I have visited.
Any insights out there? Any big fans of the OSF?
