(CNN) - Is a meal at your favorite restaurant worth more on a Saturday night than it is on a Thursday?
Some restaurants seem to think so.
They're joining a movement toward variable pricing.
It's a trend that started in the skies and could be landing at a restaurant near you, and is as simple as supply and demand.
It's an idea that's putting a whole new spin on eating out.
"Just like in the airline or hotel industry where the price might depend on the demand of that hotel room or airline seat, we introduced that same model to the restaurant industry," said Ben McKean, Savored co-founder and CEO.
Savored is a reservation websites that's built on a simple fact of life: time is money.
Like airlines, Savored offers cheaper meals for off-peak hours, so a table at 9:30 p.m. on Tuesday at the famed 21 Club in New York would cost customers 30 percent less than one for Saturday at 8 p.m.
Now considering the quality of the restaurant where dinner for two can easily cost more than $150, that's huge.
"For them it's really a unique value that is very compelling," said McKean.
But on the flip side, are customers really okay with the idea of paying more for peak dinner times once they know they can get it for less?
Peter Esmond, Director of Operations at Rouge Tomate, says yes.
"The same thing as why you go to happy hour and you go to happy hour 5 o'clock because it's early. They don't do happy hour at nine, they do it at 5:30. There's a reason for that," said Esmond.
And with the amount of money this idea is bringing in so far, it's likely here to stay.
"We're generating over $40 million a year for our restaurants and we have 1,000 restaurants on the platform so we feel that we're making a significant contribution to their businesses," said McKean.
Right now, Savored.com offers deals at restaurants in the New York City area.
