Takumi is a popular Japanese ramen house in Düsseldorf. I went around 2pm on a Wednesday and there was a long line outside the door. For a party of 3 we waited around 40 minutes. I ordered a set menu with miso ramen with pork and a side of marinated pork with rice. I also tried the fried boneless chicken piece with mayo and gyoza. The food tastes just like what I had in Japan; everything was full of flavor and nothing I ate was disappointing.
Location: Immermannstraße 28, 40210 Düsseldorf
Cost: For a ramen, a side, and a beverage came out to aprox. 15€
Side note: Gyozas are half off on Wednesdays for 2,40€
