ONE PIECE Grand Gourmet iOS: Release Date, Platforms, and What to Expect

Is ONE PIECE Grand Gourmet iOS Confirmed?

ONE PIECE Grand Gourmet iOS is the question every mobile One Piece fan is asking now that Bandai Namco has confirmed the cozy restaurant sim is heading to phones. The game arrives this week, and the App Store appears on the official platform list alongside Steam, Nintendo Switch, and Google Play. If you'd rather build Baratie Number Two on an iPhone than on a desktop, here's what is actually confirmed about the ONE PIECE Grand Gourmet iOS release — and what the publisher has not said yet.

Short answer: yes. The official Bandai Namco page for ONE PIECE: Grand Gourmet lists its platforms as "Nintendo Switch™, Nintendo Switch™ 2, Steam, App Store*, Google Play*" as of October 21, 2026. The studio's own "A Day in a Rookie Staff Member's Life" walkthrough video also closes with a "Grand opening on October 23rd, 2026" card.

Independent coverage lines up. A creator preview published ahead of launch states the game arrives October 23 for Switch 2, Steam, Android, and iOS — labeled here as player experience from an early-access build, not a publisher specification sheet.

ONE PIECE Grand Gourmet iOS Release Date and Launch Timing

The official site pins the release date at October 23, 2026. The Steam listing captured on October 21, 2026 shows something slightly different: a release date of October 22, 2026, with an unlock time of Thursday, October 22 at 10:00 PM UTC, plus an announcement noting the game "arrives October 23, 2026."

The sources use different scopes: Steam’s historical 10:00 PM UTC timestamp applies to Steam, while Bandai Namco’s official site lists October 23. The sources reviewed do not include a specific App Store rollout time for the iOS build, so check the live App Store listing for your region instead of inferring its timing from Steam.

Key facts at a glance (as of October 21, 2026):

• Developer: Kairosoft Co., Ltd
• Publisher: Bandai Namco Entertainment Inc.
• Genre: Management sim / casual
• Players: Single-player
• Steam price: $19.99 (pre-purchase, recorded October 21, 2026)
• Steam features: Achievements, Cloud, Family Sharing

What the iOS Version Actually Plays Like

ONE PIECE Grand Gourmet is not a platformer or a brawler. You play as a rookie staff member helping the Straw Hat crew turn the second location of the Baratie into the greatest floating restaurant on the seas, after impostors drag Sanji's reputation through the mud.

The loop, per the official feature breakdown and the walkthrough video, runs like this:

• Cook with Sanji. Mix ingredients and recipes inspired by characters' ideas to create new dishes, from Water-Water Meat BBQ to Sea King Penne Gorgonzola.
• Plate and build set menus. Combine finished dishes with decorations and side items to raise the value of each serving.
• Decorate the deck. Over 200 furniture, building, and decorative pieces are available, ranging from Whole Cake Island dessert themes to futuristic Egghead items.
• Grow the fan base. Characters who like your food or your interior can become regulars and keep visiting as you unlock new seas.
• Meet the cast. The official site frames the roster as a "Table For 400" — more than 400 characters drawn from across the series.

A hands-on preview described the layout tools as surprisingly deep for a budget-priced title, and admitted the restaurant can look like a mess if you don't plan your furniture placement. That's useful context for touch controls: expect a lot of dragging, tapping, and rearranging.

Price, Editions, and Mobile Caveats

The only price supported by the supplied material is the Steam figure. As of October 21, 2026, the Steam store page recorded a pre-purchase price of $19.99 for the Digital Standard Edition, which includes the base game. No App Store price point appears in any of the available sources, so anyone quoting an iOS price right now is guessing.

The official site also carries two footnotes marked with an asterisk next to both mobile stores: the user is responsible for any data charges incurred, and "some devices may not be compatible." Neither nuance appears in the Steam listing, which suggests the mobile builds have their own hardware considerations.

A few other details worth knowing before you commit:

• Interface languages: English plus 11 more, listed on Steam.
• Rating status: The Steam page showed "RP — Rating Pending" as of October 21, 2026, with mild fantasy violence and alcohol reference noted on the publisher site.
• No cross-save confirmation: Nothing in the sources mentions sharing progress between Steam and iOS, so don't assume it.
• Single-player only: The official site lists the game as a single-player management sim, so there is no co-op mode to plan around.

Practical Tips Before You Download on iPhone

1. Check the App Store listing on launch day. Since no iOS price or file size has been published, the store page itself is your only reliable source once it goes live.
2. Verify device compatibility first. The publisher's own footnote warns that some devices may not be compatible — a real concern for older iPhones and iPads.
3. Play on Wi-Fi if you're data-capped. Bandai Namco explicitly places data charges on the user, which matters more on a phone than on a PC.
4. Follow the official news feed. The Steam page has been running a "Teach Me, Tori" video series (Episode 4: Fruit Macedonia was dated October 21, 2026), which is where platform-specific announcements are most likely to surface.
5. Don't over-plan your restaurant. Early impressions suggest the layout system rewards slow expansion over cramming every decoration onto the deck at once.

Does the ONE PIECE Grand Gourmet iOS version have the same content as PC? The official site presents one shared feature set — over 200 furniture items, 400+ characters, Sanji-led cooking, and single-player management — without listing platform-exclusive differences. That said, no source explicitly guarantees parity between the Steam and iOS builds.

Which iPhone or iPad models are supported? That information has not been released. The official site only notes that some devices may not be compatible and that users are responsible for data charges, so confirm your hardware against the App Store requirements before buying.

Bandai Namco presents the iOS release with the same core restaurant-management feature pitch as the PC and console versions, but the reviewed official sources do not guarantee full content parity or rule out platform-specific differences. Keep an eye on the Steam store page and the official site for those final details as the October 23, 2026 launch window arrives.
