What the paper studied
This research investigated how artificial intelligence (AI) can be used to optimize menu design in hospitality settings to influence guest food choices and emotional responses. Using theories related to choice architecture and emotional arousal, the study tested AI-enhanced menus with different themes—sustainable, healthy, and mixed—against a baseline menu. The experiment involved 63 participants and measured their food choices, facial muscle activity (EMG) to gauge emotional reactions, and survey responses. Machine learning (Random Forest) was applied to identify which menu design features most strongly predicted sustainable or healthy food selections.
Key findings
- AI-optimized menus significantly increased the selection of sustainable and healthy food options compared to the baseline.
- Positive emotional responses (measured by EMG) mediated the effect of menu design on sustainable food choices but not on healthy choices.
- Single-themed AI menus (either sustainable or healthy) had stronger effects on guest choices than mixed-themed menus.
- For sustainability-focused menus, ease of navigation and clear sustainability indicators were the most important features driving sustainable choices.
- For health-focused menus, the presence of health icons was the key driver encouraging lower-calorie selections.
Why it matters for hospitality
This study provides empirical evidence that AI can be a powerful tool in service design, specifically in menu development, to promote healthier and more sustainable dining behaviors. For hospitality operators, especially casual dining restaurants with extensive menus and many similar options, AI can help coordinate multiple subtle nudges in the menu layout and content to guide guest choices without compromising satisfaction. Understanding which design elements matter most for different goals (sustainability vs. health) allows for more targeted and effective menu strategies. Additionally, the emotional engagement aspect suggests that combining AI menu design with atmospheric elements like lighting and music could further enhance guest experience and influence.
Practical takeaways
- Use AI to create focused, single-theme menus (sustainable or healthy) rather than mixed themes to maximize impact on guest choices.
- Prioritize menu navigation ease and clear sustainability indicators to encourage sustainable food selections.
- Incorporate salient health icons to promote healthier, lower-calorie choices.
- Consider pairing AI-optimized menus with atmospheric enhancements (e.g., warm lighting, soft music) to boost emotional engagement and sustainable choices.
- Casual dining operators with broad menus can particularly benefit from AI-driven menu design to systematically nudge guests toward better food choices without reducing satisfaction.
- Employ machine learning insights to continuously refine menu features that most influence guest behavior for your specific objectives.
