Most of the workers here are still in high school, and while service is always fast, I sometimes come across cranky cashiers (lol).
Their small sized shaved ice is more than enough for my boyfriend and I to share. What I like to do is order a baby-size, then use my Yelp check-in offer to upsize it to a small. Saves me a dollar or so every time. They are very generous with their syrup ;) It's one of my favorite spots, especially now that summer is coming up!
