This dataset was collected as part of a planned evaluation of New York City’s proposed soda portion cap policy. Data was collected in three waves. Wave 1 was conducted between January and April 2013; Wave 2 was conducted between August and November 2013; and Wave 3 was conducted between January and June 2014. A total of 11,614 adults participated.

Point-of-purchase receipt and survey data was collected from fast food restaurants in New York City, Newark, NJ, and Jersey City, NJ. The data was collected in order to measure the impact of the proposed law on the number of calories purchased and consumed. Data was collected on the food and beverages purchased, including whether a combination meal was purchased, the size of beverage purchased, and the type of beverage purchased. Additional variables collected include age, gender, race and ethnicity, and education level.

The data is grouped into four subsections:

• Point-of-Purchase Survey Data
• Point-of-Purchase Receipt Data
• Fast Food and Convenience Store NEMS Data
• Grocery Store NEMS Data
• Dietary Recall Data

Participants were recruited outside of fast food restaurants and offered $2.00 to fill out a survey and to provide researchers with their receipts. Participants were recruited outside of McDonald's, Burger King, KFC, Subway, and Wendy's.
