I met up with the Vegas Yelp folks here for a UYE while I was in town. This was only their second week venturing to the Westside. According to them, based on the growing customer base, they will continue to come on Wednesday evenings. Shaved ice is traditionally flavored with fruit syrups but these folks have all sorts of different flavors and toppings and will even do two flavors in a serving. Except when the weather turns cool I expect these folks to do well.
As a note I decided to keep to a couple of simple flavors and had coffee topped with diced strawberries. It was very good and I heard nothing but good things about all the combinations the other folks tried.
