> I wonder if the Cheesecake Factory and Applebees use A/B testing with their menus the same way Netflix uses A/B testing?

This article from Atul Gawande would lead me to believe that they(Cheesecake Factory) have probably tried it: https://www.newyorker.com/magazine/2012/08/13/big-med

They even have revenue forecasting models that take into account: weather, time of year, holidays etc and that article is from 2012.

PS I highly recommend that article for both the medicine to restaurant comparisons and the parallels one can draw to complicated systems in general like IT.
