My coworker brought me one of these one day as a surprise and what a wonderful surprise it was! About $5 for a roll. It's large but that's still an entire meal at a sandwich place and some fast food establishments.
I am not Vegan. I will never be Vegan. I respect people who are Vegan and I am happy there is some more versatility out there for you. I do not understand why it needs to be punctuated that this place is Vegan. Personally, if there was a giant stamp on the door that stated "Vegan" I would likely be deterred. I think this is an awesome conversation starter and not a big deal. Try it!
As far as the cinnamon roll is concerned, frosting aside, absolutely perfect and 5 stars in my opinion. I am pretty boring and order the Old School Roll because I like it simple. But I've tried a few of the flavors and tried their cookie dough which is quite tasty.
For the frosting though, I have to agree with a lot of other people on some of the issues. One is that it is very sweet. You can taste that the sugar isn't dissolved and it gives it a grainy texture. The second concern is their fruit frostings. I've personally tried the blueberry and I was very disappointed. I knew something was wrong because it wasn't blue. The frosting was still the same white color. This means they use a flavoring. Why not use real fruit? I don't understand that AT ALL and therefore will not order the fruit frostings. They taste like chemicals and fake flavoring and it ruins the entire experience.
I think if they could create a way to make the frosting less sweet and make them more natural in flavoring, I would give this a five star review for sure. All that said, it is still a great place to try, Vegan or not.
