National Margarita Day returns for another year Friday, Feb. 22.

To celebrate the holiday, order the 'rita that Rocco's Tacos & Tequila Bar founder Rocco Mangel has created: Margarita for Multiple Sclerosis, featuring Maestro Dobel Diamante, acai liqueur, agave nectar and fresh lime juice.

Mangel, who was diagnosed with multiple sclerosis when he was 43, dreamed up this libation for all of his locations, including Rocco's Tacos Tampa. Proceeds from the marg's sales will help fund research about the disease.

You might as well do some good while getting a little buzz.
