The Real Problem
Somchai runs a Thai restaurant in Grey Lynn. He's been cooking Thai food for 20 years. He knows every ingredient in every dish by heart.
His staff don't.
Last month, a customer asked the new waitress whether the green curry contained shrimp paste. The waitress said she'd check. She went to the kitchen. Somchai was mid-service, three tickets deep. He said yes, it does. She went back and told the customer. The whole exchange took four minutes -- during which two other tables waited.
That's a good outcome. The bad outcome happened six months ago. A different staff member told a customer the pad thai was nut-free. It isn't -- the recipe includes crushed peanuts. The customer had a peanut allergy. Somchai caught it before the dish went out, but it was close. Too close.
Thai and Vietnamese cuisines are minefields for allergens. Fish sauce is in almost everything -- and it's a shellfish derivative. Shrimp paste hides in curry pastes and stir-fry sauces. Soy sauce contains gluten. Peanuts appear in pad thai, satay, and garnishes. Coconut is in curries, desserts, and drinks. Many of these ingredients aren't obvious from the dish name.
Somchai gets 5-10 allergen questions per service. On busy nights, more. Each one requires someone who actually knows the recipe to answer -- and that person is usually Somchai, who's also cooking.
NZ's food safety law requires businesses to know and disclose allergens when asked. Most small restaurants handle this verbally, with no documented system. The accuracy of the answer depends entirely on who's working that shift. Sen Vietnamese in Auckland openly notes on their website that staff must "advise which items cannot be made coeliac-safe due to having only one fryer." That's honest -- but it highlights how much of allergen management in NZ restaurants is ad hoc.
Why Existing Tools Don't Solve This
Your printed menu might have a "contains nuts" symbol next to a few dishes. But it doesn't cover cross-contamination, hidden ingredients like shrimp paste in curry paste, or the fact that your single fryer means nothing is truly gluten-free.
Generic allergen management software exists for large food manufacturers. It's not designed for a 40-seat Thai restaurant. And your POS doesn't track ingredients -- it tracks sales.
NZ's gluten-free, vegan, and dairy-free culture is far more pronounced than many other markets. Customers expect detailed allergen information, and they expect it fast. "I'll go check with the chef" is not a competitive answer when the restaurant next door has it on a QR code.
How AI Solves This
Somchai's OpenClaw AI assistant has every dish catalogued with its full ingredient list -- including the hidden ones. Customers access it through a QR code on each table, or through the restaurant's website and WhatsApp.
A customer scans the QR code and selects their allergies:
Customer selects: Peanuts, Shellfish
AI: "Here are the dishes on our menu that are safe for you (no peanuts, no shellfish):
Starters:
- Spring rolls (vegetable) -- rice paper, glass noodles, vegetables. Served with sweet chilli (no fish sauce)
- Corn fritters -- corn, curry paste (peanut-free, shrimp-free version available)
Mains:
- Massaman curry (chicken) -- uses our house curry paste, peanut-free. Note: traditional massaman contains peanuts, but we make ours without for this reason
- Basil stir-fry (tofu or chicken) -- soy sauce based, no fish sauce, no shrimp paste
- Fried rice (chicken or vegetable) -- soy sauce based
Not safe for you:
- Pad thai -- contains crushed peanuts
- Green curry -- curry paste contains shrimp paste
- Tom yum soup -- contains shrimp/fish sauce
- Satay -- contains peanut sauce
Cross-contamination note: Our kitchen uses a shared fryer for spring rolls and battered items. If you have a severe allergy, please let your server know and we can prepare items using a separate pan instead."
A staff member can also query the AI internally:
Staff (internal chat): "Table 4 asks if the larb can be made without fish sauce"
AI: "Larb normally uses fish sauce as the primary seasoning. We can substitute with soy sauce and lime juice -- the flavour will be different but it works. This makes it shellfish-free but NOT soy-free. Confirm with the customer and let the kitchen know to use the substitute dressing."
The AI doesn't just list allergens -- it understands the recipes well enough to suggest modifications and flag cross-contamination risks.
How We Set This Up
None of this works if the AI is just a standalone chatbot with no connection to your actual business. That's why BestAI builds a custom integration program -- a piece of software that bridges your AI assistant with the systems you already use.
For this kind of setup, that means:
- Building a complete ingredient database for every dish, including sub-ingredients (e.g., what's in your curry paste, not just "curry paste")
- Creating a QR code system that links each table to the AI allergen checker on your website
- Setting up an internal staff channel so kitchen and floor staff can query allergen information instantly
- Connecting the AI to WhatsApp so customers can check allergens before they even arrive
- Building the knowledge base from a detailed walkthrough of your recipes with the head chef
Here's our process:
- We map your full menu -- We sit down with you (or your head chef) and document every dish, every ingredient, every sub-ingredient, and every cross-contamination risk. This is the foundation.
- We build the connections -- Our developers write a custom program (an API connector) that powers the QR code system, the customer-facing allergen filter, and the internal staff query tool. No manual data entry, no guesswork.
- We test end-to-end -- Every allergen scenario gets tested against your actual recipes before going live. We verify the AI's answers against what the chef confirms.
- We maintain it -- When you change a recipe, add a dish, or switch a supplier (which may change ingredients), we update the database.
You don't need to be technical. We handle all the development -- you tell us the recipes, and we build the system.
The Result
- Instant allergen answers -- customers get accurate information in seconds, not minutes
- Staff confidence -- no more guessing or running to the kitchen mid-service
- Reduced risk -- every allergen answer is consistent, regardless of who's working
- Cross-contamination transparency -- shared fryer, shared wok, and prep surface risks are flagged automatically
- More covers from allergy-conscious diners -- customers with dietary needs actively seek out restaurants that handle allergens well
What AI Can't Do Here
- AI can't guarantee zero cross-contamination -- that's a kitchen operations issue, not an information issue
- AI won't replace the need for staff to confirm severe allergies face-to-face -- for anaphylaxis-level allergies, a human conversation is still essential
- AI accuracy depends on your recipe database being correct -- if you change a recipe and don't update the system, the AI gives wrong answers
- AI can't account for supplier ingredient changes -- if your curry paste supplier changes their formula, someone needs to update the database
Who This Is For
- Thai, Vietnamese, and Asian restaurants where hidden allergens (fish sauce, shrimp paste, peanuts) are common
- Restaurants that get frequent allergen questions and rely on staff memory to answer them
- Any restaurant that's had a near-miss with an allergic reaction
- Businesses in areas with a strong GF/vegan/DF customer base (common across NZ)
