Fast food restaurants are as busy as ever during the pandemic thanks to conveniences like drive-thrus and relatively inexpensive prices. But which ones are the most popular? TOP Data has compiled information to determine the top five fast food restaurants in each of the lower 48 states. The data was collected from June 12, 2019 to June 12, 2020. Including a few months worth of pandemic quarantine in the study may have contributed to Sonic, a drive-in restaurant, being the most popular in 14 states. That doesn't mean spots like McDonald's or Subway are slacking though, since they both appear in every state's top five.
