- Phone: +43 1 533 55 30

## What to fix first
- **No structured data for the business.** (+14 points) Add schema.org JSON-LD for the business (Restaurant, LocalBusiness or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine and acceptsReservations). It is the one block every assistant reads first; the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **No llms.txt.** (no points, still worth doing) Optional today, cheap to add: a short text file describing the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business

## Fix kit: What to paste

Structured data (JSON-LD). One block in the page's head, or in the builder's custom-code slot. Replace anything that is wrong.

```

## Already right
- **robots.txt lets AI crawlers in.** There is no robots.txt, which allows everything.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all received a normal response.
- **Menu or price list is an HTML page.** Agents can read items and prices directly.
- **Booking through zenchef on your own domain.** No marketplace commission, and the guest stays yours.
- **Zenchef lets agents act only through its partners.** Zenchef's website terms (19 February 2024) forbid robots, scripts or automated systems that extract content and forbid crawling or scraping; agents book only through partner integrations a restaurant enables. Read 2026-10-15: https://www.zenchef.com/terms-conditions. An assistant that is not a partner cannot finish the step there; a direct path on your own domain works for all of them.
