Time Out says
This Tokyo Station outpost of popular sushi eatery Tsukiji Sushi Sei is located in the GranSta Dining section of the meandering station. The standout on the breakfast menu (served 7am-10am) is the tai goma dare (sliced snapper in a rich sesame dressing; pictured) set meal. Other options include braised fish with a side of sushi, and salmon belly topped with ikura (salmon roe) – all come with rice, miso soup, pickles, tamagoyaki, plus other toppings and a flask of hot stock. Add toppings to the rice, pour over the hot stock, and you’ll have ochazuke.
For lunch, the seasonal sushi and sashimi sets range from ¥1,400 to ¥3,200, and if you’re off to catch the shinkansen, grab a bento box to go.
