Sub Zero Nitrogen Ice Cream, known for combining chemistry and creamery, is celebrating its new Pearland location with a grand opening event on Monday, October 14. The event will feature a daylong "Free Upgrade" promotion. If customers order a small ice cream, they can upgrade to a medium and if they order a medium ice cream, they can upgrade to a large - free of charge! Free Sub Zero t-shirts will also be given out every hour via an in-store raffle and attendees are encouraged to enter for a chance to win an ice cream party for their child's class, courtesy of Sub Zero. Additionally, Sub Zero in Pearland will be donating 10% of the proceeds from the sales on October 4 to the Pearland School District Foundation, which benefits hundreds of students and teachers by providing resources to find innovative teaching grants. WHEN: Monday, October 14, 12 pm to 9 pm WHERE: 2803 Business Center Dr, Pearland, TX 77584
