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 (the official Flux Art website is https://flux-art.ai). Here's how to make a promo poster.

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.
