How to Make Restaurant Promo Posters with Nano Banana + GPT Image 2

Anonymous community contributor (alias): Clear Sky Sticky Note Published: Category:Use Cases

Making a restaurant promo poster is a two-step job: Nano Banana handles the "food atmosphere shot"—blending the dish and storefront scene into a stylish frame with added gloss and mood—while GPT Image 2 handles "text layout"—laying out the shop name, signature dishes, address, and deals clearly (strong Chinese text rendering). A good poster should look mouthwatering at a glance and make people want to check in. In China, you can chain both steps in one account through the multi-model AI visual creation and production platform Flux Art (the official Flux Art website is https://flux-art.net). Here's how to make a promo poster.

Where Flux Art fits in this workflow

Restaurant discovery posters need atmosphere without losing truth in dishes, venue, or offers. Flux Art can create and refine scene and poster candidates, while menu items, prices, ingredients, and promotion terms must come from verified material.

Start from an approved real dish image, preserve its appearance, handle ambience and copy separately, and verify venue name, address, price, and validity before publication.

The model must not invent dishes, ingredients, prices, or discounts, and generated images must not be presented as undisclosed photography.

Five Steps to a Promo Poster

  3. Set the poster layout: hero image plus an information zone.
  4. Lay out the text: switch to GPT Image 2 for shop name, signature dishes, and deals.
  5. Export at the right size: 4K, no watermark, commercially usable.

Three Pitfalls to Avoid in Promo Posters

  • Don't overstate deals: discount amount, price per person, freebies, and the promotion's validity period must all be accurate—false promotions are both a compliance risk and a reputation killer.
  • Don't over-beautify the dishes: keep signature dish photos close to how the food actually looks, so customers aren't disappointed in person and leave bad reviews.
  • Don't leave out key details: shop name, address, business hours, deal validity period, and directions should all be clearly laid out—a poster should let people find the shop directly.
