# Tian Bistro: Agent-Direct Score C (66.2%)

Site: https://www.tian-bistro.com
Report: https://directindex.org/r/tian-bistro.com
Scanned: 2026-10-14 (Provisional: the action test and the assistant citation check still to come; the hatched part of the bar is not measured yet.)
Tian Bistro is partly visible to agents.
An AI assistant can open the website of Tian Bistro. It finds no menu or price list, so it answers from other sites. It finds a way to book or order directly, through Zenchef.

## Direct links
- Book directly: https://bookings.zenchef.com/results?rid=387891&pid=1001&shxpid=127831 (through zenchef acting for the business)

## What to fix first
- **Structured data is incomplete.** (+7 points) Missing: address, telephone, opening hours. Guide: https://directindex.org/guides/structured-data-restaurant
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer' from marketplaces instead. Add a menu or price list page and link it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **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.

## Book or order directly

- Book: https://bookings.zenchef.com/results?rid=387891&#038;pid=1001&#038;shxpid=127831 (through zenchef acting for the business)

## Opening hours

Mo 17:30-22:00; Tu-Fr 12:00-22:00; Sa-Su 10:00-22:00

## About

- Website: https://www.tian-bistro.com
- This file follows llms.txt (https://llmstxt.org): a short plain-text description for language models.
```

## Already right
- **robots.txt lets AI crawlers in.** No rule blocks the key AI user agents.
- **AI crawlers get the page.** GPTBot, ClaudeBot and PerplexityBot all received a normal response.
- **Structured data present (Organization).** but without address, phone or hours
- **Booking through zenchef on your own domain.** No marketplace commission, and the guest stays yours.
- **Zenchef works with agents 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 may not finish the step there; a direct path on your own domain works for all of them.
