Sukiya is a restaurant where you can go to eat yummy food in Japan! It's a big chain with lots of different locations. The cool thing about Sukiya is that they specialize in a traditional Japanese dish called "gyudon," which is a big bowl of rice topped with yummy beef and onions that have been cooked in a sweet and savory sauce.
When you go to Sukiya, you walk in and order your food at a computer screen before you find a place to sit down. Then, someone brings your food right to your table! This means that you don't have to wait very long to eat, and you don't have to talk to anyone if you don't want to.
Sukiya's gyudon is really popular because it's so tasty and also really affordable. Lots of people, like students and busy workers, go there to grab a quick and filling meal. There are also other dishes on the menu, like curry and chicken bowls, in case you're not in the mood for beef.
