Tucked away in a cool alley off Cat Street, Menchirashi is the spot in Harajuku where you can slurp up some tasty house-made udon noodles without breaking the bank. The vibe inside is like an American diner with a hip Japanese twist, but don't worry, prices are totally reasonable – most dishes are under ¥1,000. They're known for their crispy tempura and yummy onigiri rice balls, which go perfectly with a steaming bowl of udon. Pro tip: go for the kake udon, add some tempura, and finish off with a stuffed onigiri for the ultimate taste adventure.
