Need statistics about restaurant industry growth over time

I’m trying to determine whether the restaurant industry has experienced a uniform increase in popularity over the past 20 years. Where can I see a graph or some statistics showing the amount of money consumers have spent on eating out (adjusted if inflation, if possible) over time?

Just a WAG, but the NRA (National Restaurant Association - ) would likely have that sort of info. If you want to narrow it down, they also have links to state restaurant associations on the red “Dining Out” tab.

yeah, i was searching out their website, but was unable to find anything specific about it.

well, there’s a very simple graph at, but I was hoping for something with more data.
