Delicious, fast, and cheap (< $10) udon by Naka-Meguro Station. Order the shrimp & chicken tempura udon at the vending machine outside (orange buttons = hot, blue = cold) and bring your ticket inside.
Tempura and udon are good!! Order by the vending machine but they do not have English menu so I guess tourists can just lucky draw their choices 👌 but food is good so it's okay! 🍜
