SARASOTA - Sub Zero Nitrogen Ice Cream on Siesta Key had the perfect treat for the day.

Ice cream frozen with nothing more than using liquid nitrogen. The founders of the innovative ice cream shop wanted to invent a treat completely customizable by patrons.

The patented process has been seen on the hit show Shark Tank and since then stores have been opening up across the country. The shop is offering 20 percent off to anyone who mentions their Ice Cream Day Facebook post.
