First, George, your roommate is a classic VCR ignoramous.
Second, Shakey's of my youngest youth was a pizza place. No doubt. That was what they did. Pizza, player piano, styrofoam turn-of-the-century hats, Keystone Kops movies, and balloons that looked like a little person, "Shakey". Then, in 1981 or so, they diversified, adding a big buffet. Kept the pizza, but cut back on the old-timey atmosphere.
