Sushi Sei is located in Plaza Senayan, Jakarta just right in the opposite of X2 Club. The interior is just right, not authentic yet elegant with their big semi-boat-like design.
I took the first bite on the salmon belly and in the same second, I was admitting in my heart that this is truly one of the best salmon belly I've ever eaten. Truly I have no idea of why did that salmon belly taste so good! Beside their thick slice, the freshness of the fish contribute most of the taste I think. It was just so so tasty.
The rolls, thick-tamago, and the ika were decent. Sweet shrimp was really good
