Last day, I went to Sukiya for the first time. Sukiya is chain store that sell beef bowl as their main menu. I had ''negitama-gyudon''. It is beef bowl with cut leek and yolk of egg. It was delicious. The yolk of egg was shining. At that time ,I was surprised at product delivery speed. The beef bowl was offered about 30secounds after ordering. I thought that it's too fast...!? I want to eat other menu next time. Please tell me your recommend menu in Sukiya.
