Mary Carroll’s has been serving brews in Babylon Village for nearly 30 years.

Owner Conor Hartnett said the restaurant’s most popular drink is Guinness.

The pub features a “Guinness” bathroom meant to feel as if you’re inside a pint of Guinness.

There are 150 whiskeys on the menu, which Hartnett said is the largest whiskey selection on Long Island.

On St. Patrick’s Day, corned beef is served aplenty and if you’re lucky, you might catch some bagpipers.

If you can’t make it on March 17, there’s more St. Patrick’s Day fun ahead: Babylon’s annual St. Patrick's parade will be held on Sunday.

There will be a big celebration with live music at Mary Carroll’s.

“Irish people, if they’re given any gift, it’s that they can socialize and have a good time and mingle with all types,” Hartnett told News 12.
