Definitely get the white gourd (wintermelon tea) at 70% sugar. At 100% it was too sweet. I should have read the Yelp reviews first (doh!).
It's nice to be able to drive off the strip and get some affordable boba milk tea. We stopped by during our stay in Vegas and wanted to get some drinks before heading back to the hotel. Kung Fu is located in a busy plaza in LV's Chinatown. We came right before closing at 12am and originally I had wanted to order the white gourd green tea, but they had run out of green tea. I opted for just the white gourd tea with herbal jelly and bf got the coffee milk tea. White gourd tea was really sugary, but the herbal jelly was able to kind of help off set the sugar a bit. The coffee milk tea was strong on the tea, but not the coffee. It tasted ok and I'm glad it wasn't as sweet as my drink. We didn't end up finishing our drinks that night. The next day, with the ice melted, the white gourd tea was a lot better.
I'll probably stop by again on my next trip out to Vegas, but I'll make sure to ask for less sugar. =P
