My 6 year old loves this place, but they are pricey. I paid $12.35 for a small "unicorn poop" ice cream with cone.

Went to the new location in worcester public market, pretty over priced just to watch someone freeze ice cream, glad i went though so i know not to go back read more

Overall I had a really good experience. The lady helped talk me through the entire process and I got to watch her make my ice cream. Was really cool seeing the nitrogen process and I was actually pretty quick. This is probably helpful because they actually make each order fresh so you can see the entire process happen. It was super cool! read more

Sub Zero Nitrogen Ice Cream - This place was unique! Reviews said they were on shark tank. I wanted to try it for something different. Impressed!!! - Desserts Near Me - Nashua, New Hampshire

Sub Zero is truly one of a kind. Amazing experience to see the ice cream made right before your eyes using liquid nitrogen to freeze it immediately. Not only is it a great experience but the ice cream is delicious and very creamy. Since it is made to order, they can accommodate any food allergy and even lactose intolerance. Give them a try, you will be happy you did! read more

I'm on a paleo diet, which means basically no dairy, no sugar... no worries, it doesn't mean no ice cream. Sub Zero has great solutions for me to stay healthy and enjoy my indulgences! Also, they are great community partners and volunteers, woman and veteran owned. Best place there is to get a sweet treat and fell great about it! read more

OMG is this ice cream good ....and so cool to watch it being made (like right out of a science movie!) There are some great themed combinations to choose from (my favorite is Magnetic Mint) or pick your own combination of base, flavors and mix-ins. I've also had SubZero cater at some summer parties at my house, and they were quite the hit for both kids and adults! read more

Rude staff, over priced ice cream. Felt very uncomfortable the entire time because of how the staff were acting. Will not be returning.

Absolutely amazing! We saw it on Shark Tank forever ago and we were excited to find one near us. The ice cream was amazing. So many different flavor options! But even better was the service! So knowledgable! She explained the entire process to us! It was amazing! Will definitely be back soon! read more

Not only is the ice cream neat to watch to be made, the product is delicious, cold and refreshing. The staff at the store is friendly, helpful, and courteous. It is worth the trip to go to Nashua to enjoy this special treat. Lots of flavors and toppings. read more

Love this place! They have great ice cream and even better service! Recommend to anyone looking for some great ice cream.

Had high hopes for this place because I've heard of similar places that were delicious, but unfortunately this place is NOT! The base and flavors used for the "ice cream" taste very fake. I got the traditional cream base with the flavors of malt and peanut butter with fudge on top and it tasted extremely chemically and watered down. There was 5 of us and none of us enjoyed our ice cream. One of the biggest problems is the textural issues with this stuff (whatever it is). It has a texture that mimics glue and ice, and it pretty much tastes like that, and I'm talking not even elmers glue, I'm talking like store brand glue. Ew go somewhere else. read more

I just love this place and their ice cream, that is made right in front of you while you wait. Speaking of waiting, since they do make everything from scratch, it does take longer than your usual ice cream eatery... so don't head there if you're in a rush. :) read more

We love Creamistry so we thought we'd try Sub Zero hoping for a great experience. We were soooo disappointed!! The base mix taste like watered down chemicals. The flavors were awful. The add ins were not quality but cheap. My stomach hurt for days after eating here. read more

I've been here with a friend who has allergies, and the choices for her were amazing. Because it's made in front of you, you always know what's in it. It's a very interesting process to watch, and the combinations are endless! read more

Sub Zero Catered our wedding and were a pleasure to work with. They created a fun memorable experience for the guests. Ice cream was delciious and they were even able to accommodate our vegan guests. They were quick to respond, easy to work with and super friendly! Overall I would hire SubZero again for catering! read more

Actually not a fan of this place... What drawn me in was of course their method of creating ice cream from scratch, right in front of you, flash frozen with nitrogen, which I've had before elsewhere and I remember enjoying it. But this place didn't cut it for me, I've had the Magnetic Mint which is made up I believe Andes Mints and and mint flavored syrup for color (like a shamrock shake at McDonald's) and toppings like Oreo and fudge. The texture of the ice cream itself wasn't smooth enough, it sort of fell apart kind of like kinetic sand. Also, the Andes Mints weren't broken down enough so those frozen chocolate pieces weren't really enjoyable and I absolutely love Andes Mints, so that was off-putting for me. This artificial mint syrup stuff just doesn't belong in ice cream, especially the amount the worker had put in. Also want to point out when the guy was making mine, he was not entirely committed to it, his eyes were toward the tv for most part and that just shows lack of care. The interior is kind of lame besides the huge tank, but I mean shouldn't an ice cream place be exciting? Just wasn't enjoying it and probably won't be back. read more

I must admit that I had my doubts. Thought it was a gimmick. But the ice cream (I had the regular cream) was excellent! Service was friendly, engaged and seemed to be enjoying themselves. Wish they had a true dark chocolate ice cream but alas .. well everything else was great. I'll be back. read more

This was my third visit, so I felt it was an adequate time to leave a review. My first visit was not too bad, my boyfriend introduced me to this place. The first time seeing the freezing process was very cool, and the ice cream was pretty good. I had the cinnamon roll sensation plus cheesecake bits and a lactose free base. Second visit was with a group of about 10 people. Everyone other than me had never been before, so it took a good 15-20 minutes to figure out what everyone wanted to order. Since it was a trip for a club, we were all paying together. Unfortunately, there was only one employee working and he insisted on waiting until everyone had decided and relayed their order to him to begin to make the ice creams. Then it took about 3-4 minutes each. That's an hour for ice cream! I can't even remember what I ordered. My third visit was today, and I was definitely less than impressed. I ordered the mint sensation with brownies and a lactose free base. The texture of my ice cream was incredibly gluey, and the mint tasted absolutely fake. After a few bites, I just didn't want much of it anymore. It also had a slightly watery taste to it, almost like the base was watered down. Totally not worth almost $6 for a small! Definitely think the novelty of sub zero has worn off. The ice cream is just okay, not a very high quality but what can you expect with flavor squirts- definitely not fresh! Unfortunately, with these prices you would think it was organic! Most likely will just bring lactose pills and do my ice cream business elsewhere. read more

This place is good...I like custard a lot and luckily they have it... its like you have to choose the flavor like butterscotch,caramel,mint etc and they put freeze it under liquid nitrogen... thats actually wonderful... make sure you select the correct combination read more

I love sub zero! You have so many flavor a to choose from! Low fat, vegan and lactose free. Peanut butter bonds is my favorite !! Definitely give it a try ! read more

A fun learning experience and excellent ice cream. I highly recommend you bring the family to Sub Zero

I was super excited when I found out there was a sugar free option... so a week before Memorial Day I made the drive and decided to give it a go to see how it would affect my sugar levels. Well... it tasted great and my sugar levels remained steady. It was great! I'm type 1 diabetic so I was thrilled to have finally found a place I could enjoy ice cream with everyone. My excitement was short lived when the week after, I made the drive again, waited in a super long line, and although I was told when I ordered that there was the sugar free base... when they went to make it... the other employee came back from out back and said there wasn't any. It was upsetting but I just thought ok, they ran out. Well... I made the drive again today and once again when I ordered, I asked if they had the sugar free option and again... they said they did have it. We ordered mine and then my boyfriend ordered his... and we paid for both. One employee started making his and then the other employee was asking a third employee how to make the sugar free option. He told him they didn't have any. ‍ total disappointment! He told us that the sugar free option has been on back order for about a month and that they keep telling them that it's coming but it hasn't come. He gave us our money back for my order but I was totally disappointed and had to just sit there and watch my boyfriend eat his ice cream for the second time. They shouldn't advertise heavily on the fact that they cater to all diet restrictions if this is a reoccurring situation. Very very disappointed! The only reason I'm even giving it two stars is because it was actually available and good the first time. read more

I first heard of Sub-Zero when watching Shark Tank and was excited to find out this ice cream was at a wedding I recently attended. It was a lot of fun to watch the initial freezing and re-freezing process. The adults were just as curious and entertained as the kids! Aside from the entertainment factor, this was the creamiest ice cream, so delicious. Thank you Mark and Rita. You have a great business and product. In addition, you have super friendly personalities to go along with it! I wish you many years of continued success. read more

Brought our Youth Group in a few weeks ago and a few of the kids had allergies, all of which were accommodated. Always a cool experience coming here and we get to try something new every time we go. I would highly recommend checking out Sub Zero! read more

great ice cream. very informational. Awesome service! prices seem the same as anyother ice cream shop

My Fiancé and I have been going here for about 2 years now. Today we had the worst experience ever that almost cost my fiancé her life. We know the menu well due to her SEVERE dairy allergy. She will go into anaphylactic shock. It's not "lactose intolerant" where she will get the runs and call it a day. We like the place because they cater to her allergies and ALWAYS check. Today, not so much. My fiancé ordered her ice cream with all dairy free toppings and flavorings. She, of course, over emphasized her allergies and told them the severity. He clearly did not take it seriously as he replaced one of her toppings with another topping that was made with dairy. He did not inform us of the change either. It just happened with no communication. Luckily, my fiancé noticed something different and asked. His response was "oh these toppings are interchangeable, it's fine". They may be interchangeable flavor wise, but one had Dairy and the other does not. He didn't even bother to check or even ask if it was okay. When we told him this, he responded with "I just gave you what you asked for". As if it was our fault? We asked for no dairy. And you changed a topping to one with dairy despite the allergy notification? Had my fiance not checked prior to taking a bite, I would be writing this in the hospital room. This is inexcusable. This employee should be absolutely ashamed of himself. Not only for his act, but arguing and casting the blame on my fiancé for "getting what she asked for". Unbelievable. read more

I ordered coffee icecream with heath bar. I got a small and it filled half the cup and didn't even reach the top of the cup. They put the last of the heath so I got one chunk of heath. It tasted like almonds and I will make sure to never go here again. Complete waste of money. read more

Unique way of creating ice cream. Flavors and toppings give plenty of options.

honestly the ice cream is really good and it's fun to come every once and a while but the staff is just so rude. i went here 4 years ago and haven't come back since because of this. i decided to give it another try tonight but the same exact thing. it's supposed to be a fun experience and when you are greeted with anger it kills the vibe. i understand all businesses are doing their best but this could deffinetly be improved a lot read more

We had Sub Zero provide an ice cream bar at our wedding over the summer and it was phenomenal! They were very friendly and a huge hit after dinner. They even let us use some liquid nitrogen to get cool mist shots with our photographer! We were very pleased to have them there and their ice cream is delicious. read more

I saw the Shark Tank episode and was excited to see a franchise in our area. Any place that approaches serving food in a unique and fun way is the type of establishment that deserves the business. So entertaining for kids, who are already out-of-their-mind happy for getting ice cream! The flavors and combination choices were endless, so I decided to go for one of their own creations from their "Sensations" list. Can't remember what it was called, but I know it had key lime flavoring and cheesecake chunks...extremely yummy. Very cool watching them blast the chosen ingredients and cream in a stainless bowl with the liquid nitrogen- it was quite a show. As for the quality of the finished product, while it wasn't the absolute best number one ice cream I've ever had (although very, very good!), it maintained a freezing cold temperature the whole time I was eating it. No melted mess in the bottom of my bowl was a huge plus. The eating area inside of Sub Zero was very clean, and we sprawled out on the comfy seating and watched Sponge Bob on their flat screen. The employees were all friendly and took plenty of time to explain how it was made and gave flavor suggestions. One young man was not only enthusiastic about the product, but took it in stride when the freezing tank stopped working and had to finish it with their small catering tank. Glad they have a back up plan! We would definitely go back again. read more

Im sorry but your icecream has gave me a stomach ache and I didnt feel good for the whole night. I dont know if it was the Nitrogen?? but i got MILK AND CREAM FREE ICECREAM. Anyway, good ice cream when its going in but when its actual in, you want it out. read more

We had Sub Zero come out to a graduation party and couldn't have been more pleased. People loved the presentation with the liquid nitrogen, but more importantly loved the ice cream. Rita was great to work with. She responded quickly and was very organized. Would highly recommend them for any catering event. read more

Definitely gets points for being original the ice cream being made in front of you is really cool and it taste pretty good too would go back here not the best ice cream in the world or within the radius would much rather go to the big one but lots of fun to bring the kids to and see the ice cream be made read more

This place dope af. Liquid nitrogen to make ice cream is probably one of the coolest ideas ever.

Sub Zero catered our wedding, nice show for the Grand-kids and our Guests. Mark and Rita did a great job with the ice cream. Very nice Folks very out going. Highly recommend them for all your outings. read more

Store is so frequently out of what I go there for it almost isn't worth being an option. They offer custard and it seems to almost never be available. I complained that this is a too frequent occurrence and the staff jokes with me about other items they run out of consistently. If this is happening so often then stock more! All excuses aside it can be summed up as poor management. read more

great service! very cool experience! definitely recommend if you're in the area.. have never been any where like this, take your kids they'll love it. read more

I went in with my family about 1:30 in the afternoon. There was a group of four people ahead of me being served by two employees. There appeared to be three employees working. None of them greeted us or acknowledged that there were people waiting. We waited about 15 minutes to be waited on. I tried the lemon Italian ice while others in my family all got the mint ice cream. The lemon ice tasted very artificial. It was not lemony at all. But the texture of the ice was great. The ice cream was ok.. nothing special. The prices are high, as I expected they would be. It is exciting to watch, but I will not be back. Waiting that long for ice cream in a practically empty place is not my idea of a fun time. read more

After all of this hype I thought that this would be halfway decent but the "ice cream" was basically spoiled yogurt. Being a mother of 5 close to 30 dollars for an ice cream is not the best for my wallet. The people were nice but if I wanted a science lesson I would go back to school. Not impressed. read more
