Restaurants, food trucks, and cafes are increasingly employing artificial intelligence to generate images for their menus and marketing materials. However, this trend has led to diners recoiling from the resulting visuals, which are often described as strange, shiny, and disturbing.

The phenomenon has gained traction online, with social media users dubbing the AI-generated food pictures 'AI food slop.' Consumers report encountering these images on menus and flyers, noting that upon closer inspection, the food depicted appears unnatural. Meats can have an odd texture, pasta may look rubbery, shrimp can resemble unusual creatures, and sauces sometimes appear applied unnaturally.

Adaeze Onejeme, an advertising sales worker in Los Angeles, recently observed what she called an 'AI flyer epidemic' at a Hollywood night market. She noted that while the images initially seemed to depict real food, closer examination revealed inconsistencies. "I was like, 'Those don't look like chicken nuggets. Those don't look like typical food that we eat,'" she told CNN, ultimately choosing vendors with traditional photographs for her purchases.

This distrust can be detrimental to smaller establishments. Grind & Unwind, a family-run cafe that opened in San Francisco's Haight Street in May, faced social media backlash after using AI-generated images of its food and drinks on its storefront. Owners AJ and Lyndsey Lozano stated the images were intended as a temporary marketing solution while they managed the business opening and raising young children. However, critics labeled the posters 'AI slop' and accused the cafe of misleading customers.

The backlash extended beyond the internet, with the cafe's awning being spray-painted with graffiti in July, resulting in a repair bill exceeding $700. Reddit users mocked the AI-generated focaccia, comparing it to a loofah or a lung, and an iced coffee was described as looking like it was wearing 'fishnet stockings.' One commenter expressed a common sentiment: "Any fake images on a menu make me think their actual food is not good enough to be shown."

The cafe removed the AI posters on July 6 and replaced them with displays of its real pastries. Its homemade banana bread and chocolate chip cookies have since been selling out regularly.

Psychological research suggests humans are particularly sensitive to discrepancies in food imagery. Alexander Diel, a psychologist at the University of Duisburg-Essen, explained that because food is crucial for survival and can easily cause illness, people are highly attuned to anything appearing 'off.' This sensitivity may be linked to an evolutionary-driven disgust response designed to help avoid contamination. Diel's research indicates that slightly imperfect AI food images can evoke a greater sense of unease and be perceived as less appealing than obviously unrealistic or genuine food photography, potentially due to the 'uncanny valley' effect.

Food photographers also note that customers possess an intuitive ability to recognize authentic, appetizing food. "There's something wrong, and you might not be able to put your finger on it, but you know it when you see it," said New York food photographer Emily Hawkes.

Despite the negative reception, the financial appeal of AI-generated imagery is significant for restaurants facing economic pressures. The National Restaurant Association reported that 42 percent of operators said their businesses failed to turn a profit in 2025, and 26 percent were using AI, primarily for marketing. For cash-strapped businesses, generating a menu of images quickly can seem more attractive than hiring a professional photographer.

However, the tactic may alienate customers. One Reddit user stated a preference for a "blurry cell phone picture" if it proves the restaurant has the actual food. The core of the backlash appears to stem from a simple question posed by another user: "Why can't they just use the REAL FOOD?"

The danger, experts suggest, is that bizarre AI imagery can create suspicion, leading diners to question what a restaurant might be hiding and whether the actual food will meet expectations. As Hawkes put it, "A thoughtful photo of your food with your iPhone is going to be better than whatever AI is going to generate because it's your food."
