Story & Management Systems Revealed in Hands-on Footage

On October 16, Japanese streamer Retoruto published an extensive early access playthrough spanning roughly 2 hours and 24 minutes. Below are key systems and narrative beats observed in the footage.

Story Notice: Contains minor spoilers for the introductory Fake Baratie incident and early progression.

The Player’s Restaurant: ‘All Blue’

Players begin by customizing their rookie staff avatar and choosing a name. Early guidance is provided by Torii, a talking bird robot companion.

The prologue centers around the Fake Straw Hats (led by Demaro Black) running a fraudulent “Fake Baratie.” When their tyranny damages both Carne’s vessel and Luffy’s party, Luffy and Sanji step in to resolve the crisis. Following the incident, players establish a new restaurant—which players can freely name. In the preview stream, the player christened it ‘All Blue.’ From there, your culinary voyage begins as you assemble scattered companions across the seas.

Recipe Creation & Set Menus

Menu development draws inspiration from ideas pitched by Luffy, local villagers, and various characters. Confirmed dishes in footage include Bone-in Meat, Pilaf, Hamburgers, Wasabi Sushi, and Sashimi. Once prepared, crewmates taste-test each recipe, gaining EXP and leveling up based on dish quality and preference.

Each dish can be customized with specific tableware, color palettes, cutlery, and decorative accents. Grouping dishes into full Set Menus (Main Course, Side Dish, Dessert, Drink) directly influences selling prices and guest satisfaction. Torii also offers an auto-recommendation feature for optimal set combinations. Later, bringing Nami on board unlocks a takeout stall for Pirate Bento boxes and a tourist ship dock to expand customer flow.

Vessel Renovation & Crew Quarters

Your initial eatery starts aboard a damaged vessel requiring repair. Arrange dining tables, serving counters, and open decks to optimize guest flow. Enlisting Franky unlocks larger structural renovations. Beyond marine-themed flooring, aquariums, and animal resting spots, you can host partner merchant stalls such as Ipponmatsu’s weapon shop and an eyewear boutique.

Crew management includes personal break rooms and joint training sessions powered by Special Training Points. Scouting beloved crew members like Luffy, Zoro, Nami, and Franky directly enhances both front-of-house service and culinary capacity.

Maritime Exploration & Guest Relations

Exploration takes your crew to iconic East Blue locales, including Foosha Village, Shells Town, Syrup Village, Orange Town, and Loguetown. Deploying Luffy and companions into these zones allows them to smash field obstacles to collect fresh cooking ingredients, furniture blueprints, and rare items.

Prominent characters visit as dining patrons, including Koby, Alvida, Buggy, Jango, Hachi, and Gaimon. Gifting them bouquets or wanted posters, or fulfilling their special requests, converts them into loyal Fans. High-profile VIPs—such as Helmeppo, Morgan, Smoker, and Mihawk—require satisfying rigorous food taste and venue ambience criteria.

Culinary Duels with the Fake Baratie

The rival Fake Baratie periodically disrupts operations by dumping debris into your waters. To overcome them, players enter judged cooking showdowns, tailoring entries to specific themes like flavor intensity, affordability, and set harmony. Victories clear sea routes into brand-new waters, including the ‘Sea of Four Seasons.’

Note: These observations are based on a pre-release build. Terminology, balance numbers, and feature details may vary in the final retail version.

Grand Gourmet centers on Kairosoft’s signature simulation loop: gathering ingredients, inventing recipes, and expanding your floating restaurant deck by deck.

Sanji plays a central role in recipe R&D. Players select ingredients based on character suggestions to assemble dishes—such as ‘Mammoth Meat BBQ’ and ‘Sea King Penne Gorgonzola’—alongside special recipes inspired by Devil Fruit powers. Sea expeditions reward rarer ingredients, steadily unlocking broader recipe trees.


Interior Decor Drives Guest Retention

Over 200 decorative items, furnishings, and architectural structures are available for placement. Thematic collections range from Whole Cake Island-inspired pastry decor to futuristic Egghead fixtures.

Interior design directly impacts patron behavior: invited characters are more likely to become regular customers if the room matches their aesthetic preferences.
