"It's a small tiny place, more likely to grab some good sushi and take away. Quality is very good (I am travelling often to Asia and eating there real genuine sushi). Ingredients are fresh, good quality and prepared with care. Generally speaking, sushi in San Sebastian is a bit overpriced, this place is not an exception. There has been a boom of this kind of in the latest years, and these places, know how to make the most of it. SUMO is one of the first sushi places I remember, opened in SS. Summing up: good quality, portions correct/regular for a sushi place, staff very friendly and helpful, very convenient location in SS downtown. A place were I go, when I feel the whim for some sushi and want to take it away. Highly recommend!"
