''If you’re looking for a deal that’s a little trendier, head to Sub Zero, the country’s first liquid nitrogen ice cream franchise. The chain uses -321 degree liquid nitrogen to hand mix (and freeze!) custom orders, which take about 2 minutes each to come together. Just like Carvel, Sub Zero is offering a buy-one-get-one-free promotion from 2 p.m. to 6 p.m. at participating locations."
