St. Patrick’s Day is the most popular day of the year at most Irish pubs and restaurants in the U.S., but the biggest crowds might not come together in the cities you would expect.

According to data from the location intelligence firm Gravy Analytics, the No. 1 Irish bar in the country isn’t located in a city with a large Irish population, like Boston, New York, or even Chicago. The busiest Irish bar in the country is actually located in Atlanta, Georgia.

To come up with its list of the top 50 Irish pubs and restaurants, Gravy’s data science team analyzed the highest average daily consumer attendance at venues from July 2017 to January 2018.

“While bars understand that St. Patrick’s Day brings in a crowd, and jewelry stores know that Mother’s Day means higher sales, this is the first time that it’s proven through data,” said Gravy Analytics CEO Jeff White. “Our data exposes the relationship between events or holidays and consumer behavior—both expected and unexpected.”
