I noticed people grabbing boxes of this stuff at the Tokyo airport, and now I know why. The matcha nama is heavenly! It's rich and melts in your mouth. Unfortunately, that also means it has to be refrigerated and Vegas is at an all-time hot streak. The shop attendant kindly wrapped it in temperature-controlled wrapping though, which would help it last for six hours.
We also found Royce at the San Jose Mitsuwa for those Yelpers in the Bay Area.
