Oldest continuous with same owner I would bet are Cap'n Flints (still open right?), and The Restaurant,; both opened in '73. Jim passed away in 2014 of course, but Susan is still running this family-owned business. http://www.therestaurantfortbragg.com/

Cafe one was build around 1959 as Mary's, then AdaBelle's then Cafe One. Lee's Chinese used to be the Welcome Inn Cafe. I don't know the year. The Restaurant used to be an Italian Restaurant, but I don't know what it was before that. These were all before 1960. Jim Larson opened the Restaurant in 1972, I believe.

Since none of those are in town (am I being too literal?) would it be the Restaurant or Egg Heads, I know both were here in 1987 when I moved here.

I would say The Restaurant.
