Mr. Z is located next to Hong Kong Garden Dim Sum and Sushi Takashi. My friend and I visited Mr. Z on 8/18. Mr. Z is in the soft opening phase with the grand opening coming shorty per the cashier. Unfortunately the full menu is not available yet. Only menu items were standard powder slushes and a few milk teas. I got an oolong milk tea with no sugar and boba. The milk tea was decent. The boba is not cooked in longan honey like other shops however it is still slightly sweet. I'd like to try the Wintermelon oolong tea and the chrysanthemum tea when available. The interior is simple with the store having a zebra theme(hence Mr.Z) but one significant improvement is needed. Please get a garbage receptacle! Also Mr. Z doesn't have stamp cards. Las Vegas has gotten many boba shops recently and I wish Mr. Z. best of luck.
