I had the spicy beef noodle soup and almond milk tea with boba. I wasn't really a fan of the soup flavor; it really couldn't compare to the authenticity of those which you would find in the 626 of socal. It was kinda sour, kinda spicy. Not the hearty beef noodle soup I was craving, but the actual pieces of beef were pretty good. I did sample my sister's dish--can't remember what it was, but it consisted of dry noodles, fish sauce and a sweet, bbq pork--and I definitely liked hers better. So I wouldn't rule out the restaurant completely, but I wouldn't recommend the beef noodle soup. The boba and tea were pretty good compared to the other places I've tried around HEnderson/LV.
I would definitely want to come back and try more of their dishes!
