Meatball lovers unite. The humble meatball is being transformed for one day only — on March 9, for National Meatball Day. (Who knew?!)

The $100 meatball will be available at Davio’s Northern Italian Steakhouse at 447 Lexington Ave. Created by executive chef Juan Tourn, it’s made with Wagyu beef, truffle Caciocavallo cheese, foie gras, winter truffles — and topped with a creamy shallot and champagne sauce.

It’s an over-the-top version of their kobe meatballs. It is paired with a glass of 2012 Prunotto Barolo.

We hear…that restaurateurs Tal and Yagur Sheinman, of Resette, are co-owners of Root Out, a root beer flavored Canadian Whiskey favored by celebs like Josh Lucas, musician Albert Hammond Jr. of the Strokes, and country singer Luke Bryan.

The drink, exclusively distributed through D&S Beverages, debuted at this past weekend’s South Beach Food and Wine Festival.
