Time Out says
Not easy to find, Sushi Express is under the Sony Center courtyard in a passage to the S-Bahn. But the hunt is worth it for tasty sushi, sashimi and assorted delicacies to be plucked off the conveyor belt. The temptation is to keep grabbing, but don't worry, from noon to 6pm Monday to Friday all sushi and rolls are half price. Hot dishes and lunchboxes are also available.
