An interesting observation from Tom Fitzmorris of www.nomenu.com
"On this date in 1960, the Food and Drug Administration approved sale of the birth control pill.
That changed many things, among which was the restaurant business. Dating suddenly became much more urgent. People who might not have had a particularly deep interest in fine dining started going out to dinner more often, to get the ball rolling. What came of that was a new category of restaurant with an interesting environment but unchallenging food. Burgers, even. It gave birth to the category that stretches now from TGI Friday's to Houston's."
Never thought about it that way but Ya, I can see that happening.
