Flux ArtMaking 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 all-in-one AI image/video model aggregator Flux Art (official sites: https://flux-art.ai and https://flux-art.cn). Here's how to make a promo poster.
I run local restaurant marketing, and promo posters are key to driving foot traffic. Demand for restaurant marketing visuals is huge, and AI photo editing has gone mainstream—Meitu's domestic monthly active users hit roughly 266 million by the end of 2024 (per Meitu's financial report). A poster with no appetite appeal and messy information won't bring anyone in, no matter how widely it's shared.
For a BBQ restaurant promo poster, I first used Nano Banana to add a glossy sheen to the signature grilled-meat shot and blend it into a warm-toned atmospheric background, then switched to GPT Image 2 to lay out "shop name + signature combo + price per person + address" with clear, well-structured Chinese text. My rule for promo posters is always: food that tempts you, information that's clear, atmosphere that pulls you in.

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.
