I tried Matcha & Seafood flavor Cup Noodle, went on sale January 23 in Japan.
I have been curious about this new flavor, like "Matcha noodles? Seriously? What does it taste like?" Turns out, it is not as bad as it sounds. The noodles are pale green, which seem to be infused with matcha. The soup is also green, though tastes like original seafood Cup Noodle. Actually there are no flavor of matcha or green tea as I expected.
If you happen to be in Japan right now, you should try this once. Available in supermarkets and convenience stores.
