One food overwhelmingly voted best way to wrap up one night stand

Can you guess?

Yup... PIZZA!

The Today Show summarized:

Three quarters of those polled in a recent Yelp survey said pizza was their top choice post a little one-night stand action. Tacos came in "a distant second," according to Yelp's press release about the poll, which surveyed 2,000 single American millennials.

In addition, Food and Wine points out:

Participants in the survey were asked to choose foods that would make their romantic partner seem more attractive (they were allowed to select all foods that appy): The top four choices were pizza (59 percent), 
ice cream (50 percent), pasta (44 percent) and tacos (43 percent).
