I went to the one in Aiken, SC and the line was very long - but they had it so well organized it moved quickly.
The staff obviously had been instructed to give red carpet treatment to us, and they did not stint on the meals.
They charbroiled t-bone steaks in front of you, as well as the normal wide selection from A-Z - salad bar to dessert bar.
What a productive use of advertising dollars, rather than newspaper or television ads!!
(There were radio ads, though, to reach local markets with the offer.)
Tremendous good will was generated.
