I came here half a year ago, while in Vegas and came again recently. Being from Seattle, there is nothing like this back home. I've only had it while on travel (Vancouver BC being the closest, SoCal, HK, Taiwan) so definitely haven't had a ton. While this place isn't as good as in Asia (5 star), I think it's still yummy. I've tried the green tea and black sesame shaved iced. Green tea is good per usual, and the black sesame did not disappoint. I was a little skeptical but the black sesame was full of flavor! I don't really think fruits complement the shaved ice too much (in my opinion). I got green tea w/ strawberry and red bean. I think the red bean with the green tea shaved ice was good, but not so much the strawberry. I would also skip on the condense milk drizzle.
I would come again if I was already in the area. It's off the strip in "Chinatown." I'm not sure where Chinatown starts and ends, but it's on Spring Mountain Road.
