Tokyo Bay Shiomi Prince Hotel (2-8-16 Shiomi, Koto-ku, Tokyo) is holding a three-day limited summer buffet — "Summer Buffet 2026: SHIOMI Fish Market" — at its first-floor Restaurant & Bar TIDE TABLE Shiomi, from August 13 (Thursday) to August 15 (Saturday), 2026. The event is themed around the energy of a fish market, with fresh tuna and seafood shipped directly from Toyosu Market taking center stage.
One of the highlights of the Summer Buffet 2026 is a tuna-cutting performance show — a live demonstration that also proved popular at the GW dinner buffet. Under the "SHIOMI Fish Market" concept, chefs fillet fresh tuna and other fish right before guests' eyes, creating a lively and memorable atmosphere. The tuna is sourced from Ishiji (石司), a Toyosu Market wholesaler known for its expertise in selecting and aging premium bluefin tuna. From freshly cut sashimi and hand-pressed sushi to a customizable seafood rice bowl ("kaisen nokkédon") where guests pile their choice of toppings, the event offers a full celebration of the sea.
A cutting service is also on offer for dishes such as domestic roast beef with two sauces, tuna kama garlic roast, and bone-in roasted lamb, all carved tableside by chefs in classic hotel dining style.
The venue also features a teppanyaki corner where squid, grilled corn, and summer vegetables are cooked on the griddle, the sizzling aromas adding to the market atmosphere. A shaved ice corner lets guests choose from four fruit-pulp syrups — strawberry, mango, melon, and blue Hawaii — for a cool summer treat.
The kids' corner includes playful items such as takoyaki gratin and tornado sausages, while the dessert corner rounds out the meal with options like choco banana, petit cream puffs styled as takoyaki, and mini roll cakes with a shaved ice motif — a full summer festival feel from first plate to last.
A room-and-buffet stay package is also available for the same period, with access to the hotel's large communal bath (including sauna) and a breakfast buffet the following morning.
