Fans have touted the restorative benefits of matcha for years. So what if this Denny Regrade newcomer—part of a Japanese chain of cafes—churns the healthful green tea powder into chartreuse-hued ice cream? Scoops of it cap off an already decadent parfait of layered matcha pudding, soft serve, cornflakes, red bean paste, and mochi balls. It’s a perfect balance of bitter and sweet, much like Nana’s other matcha-everything beverages and dessert offerings.
