I was in the Centennial area the other day and stumbled upon Perfect Scoop! I haven't been to their other location down south in a couple years. Wasn't really feeling like getting anything for myself, so I just went in to get ice cream for my dog! They only have one flavor right now - honey banana peanut butter and 1 scoop is $3.95. My dog loved it! She would have eaten the whole thing in one sitting, but one whole scoop is actually a pretty big portion for my corgi. She'll have leftovers for the next day! :)
On another note, while I was waiting for my ice cream, there were 2 customers who were vegan and they were asking one of the employees about the vegan ice cream. He was nice and polite, but I could tell that he didn't really know much about vegan foods as he kept answering "uh i don't know" or "i'm not really sure" to their questions. If you're going to work at a place that really advertises their vegan products, you might want to do some more research.
