A classic example for not judging a book by its cover. What you see on the outside is a non-descript, ugly red brick. What you get on the inside is a fantastic sushi train restaurant with an exquisite menu. The quality of the sushi is excellent and the taste even better. They have a good sake range too.

Totally unassuming from outside, however DO NOT miss this Japanese gem! The food is fresh, fast and delicious! Tuna Tatami and Mochi were amazing. Reasonable prices, cute interior and polite Japanese service. Order on the iPad and your food is delivered by a 'train'! Loved it!

You would walk right past Kosaten and not realise it even exists! Do yourself a favour and stop in here for lunch or dinner. Shame they don’t do ramen for dinner unlike traditional Japanese but that didn’t stop me from ordering a lot of dishes! The dishes were fresh, you could clearly see they take a lot of pride in their presentation, definitely recommend! The choc roll and ice cream was a winner desert!

You’d think you were in Japan with the standard of Japanese food here. Nicely flavored, nice selection of food. I loved how the food came out on a sushi train like thing.

Very authentic Japanese food. Food come out on a train format and self order on machine at the table. Very interesting experience with good food. Price are on high end, but worth it. Steam egg had lots of seafood, very surprise and very good. Dessert is good too. Fried pumpkin tofu is very good. Eel is very tasty. Plenty of parking nearby. Walking distance from city. Staff are friendly too. Need to use machine to call staff if needed. Recommend booking ahead if wanted to sit inner area.
