Complete Food Allergy Safety Guide
Your comprehensive guide to dining safely with food allergies and intolerances. Learn how to navigate restaurants confidently with Happy Munch's smart allergen detection.
⚠️ Important Safety Notice
Happy Munch is a technology tool designed to help you navigate menus, but it is NOT a substitute for direct communication with restaurant staff about your allergies.
Always verify all food ingredients and preparation methods directly with your server or the restaurant manager before ordering.
🍽️ Best Practices for Restaurant Dining
Before You Go
- Call ahead: Contact the restaurant during off-peak hours to discuss your allergies
- Check online: Many restaurants post allergen menus on their websites
- Choose wisely: Select restaurants with good allergy protocols and reviews
- Time it right: Avoid peak hours when kitchens are busiest
- Bring backup: Always carry safe snacks in case options are limited
At the Restaurant
- Speak up immediately: Inform your server about allergies before looking at the menu
- Be specific: Name each allergen clearly - don't just say "I have allergies"
- Ask for the manager: Request to speak with the chef or manager for serious allergies
- Confirm understanding: Have staff repeat back your allergies to ensure clarity
- Get it in writing: Ask servers to note allergies on your order ticket
When Ordering
- Keep it simple: Choose dishes with fewer ingredients when possible
- Avoid risky items: Fried foods, sauces, and desserts often contain hidden allergens
- Request modifications: Ask for sauces and dressings on the side
- Double-check: Verify your order when it arrives at the table
- Trust your instincts: If something seems wrong, don't eat it
