About this site

onepiecegrandgourmet.online is a fan-made information hub for ONE PIECE: Grand Gourmet, the restaurant management simulation developed by Kairosoft and published by Bandai Namco Entertainment. The game launched October 22–23, 2026 on Nintendo Switch, Switch 2, Steam, iOS, and Android — and this site exists to document how the game actually works, in depth.

Here's what we cover: the full gameplay systems (gathering ingredients, learning recipes with Sanji, composing set menus, adventuring for more), the 400+ character roster and how themed decor attracts specific characters and turns them into regulars, notable dishes from Water-Water Meat BBQ to the Devil Fruit-inspired creations, the Baratie Number Two setting, and practical beginner guides for your first hours in the kitchen.

We're players first. Every guide is written to answer the question you'd actually ask a friend: how does the decor attraction system work, what should I prioritize first, how do I get the characters I want through the door. We keep facts tied to what's confirmed — official announcements, storefront listings, and in-game testing — and we say so when something is still unconfirmed.

This is an independent, unofficial project. We're not affiliated with Bandai Namco Entertainment, Kairosoft, or the ONE PIECE rights holders — see our disclaimer for the full details. If you spot something wrong or outdated in a guide, let us know and we'll fix it.
