10/10When I want to treat myself to a special lunch, I head straight to Seisan and get the chicken gyoza and the Hot Philadelphia roll, a tempura flash fried roll with salmon. Both of these dishes are perfect for those who may want a cooked option. I love sushi, but also enjoy their other offerings. My server was so friendly and efficient. Thank you for a wonderful lunch!

Very expensive for what it is. Very very fresh sushi and ingredients but vegan sushi is absurdly expensive to get only cucumber, avocado and mango. Creativity lacked a lot of

I had a fantastic experience at this sushi restaurant! The sushi was incredibly fresh — every bite was full of flavor and clearly made with high-quality ingredients. The environment was excellent: clean, beautifully decorated, and with a calm, relaxing atmosphere that made the whole dining experience even better. On top of that, the service was quick and super attentive. The staff made sure we had everything we needed without ever feeling rushed. Definitely a place I’d recommend and return to!

They have a great sashimi and appetisers selection which I hope to return to sample more as they were delicious! Only let down was the Uramakis, well below average especially for their soft shell crab one.

10/10The first time my friends and I went to Seisan, we were all very impressed with the ambience, the delicious and fresh sushi and sashimi, and the attentive service. The next time I went, the wait staff even remembered where I sat and if I’d like the same table! I’ve been going back very regularly since, introducing many friends to this place. The 50% discount is a huge bonus too, which keeps me going back for more!

9.5/10I enjoyed my lunch here so much, I came two days in a row! The food is of great quality and the servers provide excellent service. With the Fork discount, it's a terrific value. I dropped one star for ambience because the background music is of varying genres making for a disjointed dining experience. Something soft and non-obtrusive would be ideal in this beautiful setting. No worries though, I'll be back soon!

This is my favorite sushi spot in Lisbon. It was a drizzly day today, so I stopped in for miso soup, an order of chicken gyozas, a Hot Philadelphia roll (the bomb!) and a cup of warm sake. Service was friendly and the food was served promptly. From past experience, I know to sit against the wall on one of the built in seats or in one of the gold chairs. Those brown velvet chairs, while pretty to look at, are the most uncomfortable dining chair ever. I saw others struggling to get comfortable and I pitied them. Other than that, the dining room and ambience are lovely.

Fantasic everything from the sushi to the service to the ambiance! I have tried so many sushi places in Lisbon and this is my number 1 so far! Perfectly done with big chunk of fish (fresh) and not too much rice. Service is attentive, and the restaurant (inside a hotel) is gorgeous. Overall great value for what you get. If yo want to pay less expect lower quality fish, lots of rice, and not as much variety.
