Hello all our fans out there. Big Announcement. First, We WILL continue doing Catering and STEM programs as a Catering Only franchise going forward. So all those schools, camps, venues, etc. We are still here for your needs.
However, we are in the process of looking for a buyer for our Nashua, NH - Sub Zero Nitrogen Ice Cream brick and mortar location. After 12 years in the owners are moving on to their next venture.
But, we hope to have someone continue the Sub Zero tradition here in Nashua! We plan to be open for about another month (mid/end of Sept.) So if you have rewards points or gift cards, please come by very soon to use them.
We are also closing our Sub Zero Ice Cream - Manchester location (unless someone wishes to take over that location!) on Sept 6th so come use those points and gift cards there too.
It is bitter sweet. We appreciate all our loyal customers over the years. A huge Thank You to all those who helped build the business from the ground up. Our awesome staff currently and through the years, customers and friends.
If you always wanted to be in the ice cream and catering business, make people smile, please text 603 320 1120 and say you are interested in learning more about the Sub Zero store for sale. This is a turnkey opportunity for the right person. You could be the one to keep this in downtown Nashua and/or Manchester! Comes with all of NH as a catering territory, plus we will continue to be there to help mentor. If you didnt know, this was featured on too! More to come on a last day at the Nashua location soon. Thank you all again! Help keep Sub Zero going!!
