We tried a restaurant where a 7-course dinner made from food scraps costs $21 - take a look inside

21 Greenpoint in Brooklyn, New York has a special dinner service on Sundays.

For $21 per person, you get anywhere from five to eight surprise courses, including items like mushroom pesto flatbread pizza and seafood stew.

And every dish is made with ingredients leftover from the week.

The goal of the Sunday service is to reduce the restaurant's food waste, according to owner Homer Murray (son of Bill). Nationwide, about 50% of all produce in the US is thrown away, which adds up to some 60 million tons (or $160 billion) worth of produce annually.

"We're concerned with the idea of food waste - all the stuff that gets thrown away," Murray says. "It seems like a crime against humanity, to see this food being tossed out."

We decided to try it last weekend. Check out our visit below.
