"The Yumini offers a large choice of Sushi and Grill dishes. You order on an I-pad 5 items, either sushi, meat, soup, noodles, vegetables, or drinks. After every other 15 minutes you are clear to continue with another order, always 5 items at a time. It is like a buffet coming to your table. The food is fresh and tasty, At the Yumini you avoid the type of asian buffet where food can sit for a while in the trays and get stale and loses flavor.Service is very friendly and very fast. There is a flat rate of 24 Euros p.p. for all you can eat. Drinks are extra of course. It is great to have such a variety of food, and as the portions are small you can try a lot of different stuff. As there are very few places in Siegen to eat the Yumini is definetely a good choice. In case you are not into sushi, don't worry. There are many warm dishes of meat, and poultry, kimchi, salads, etc. Highly recommended."
