# Ơ Bistro: Agent-Direct Score B (76.3%)

Site: https://www.obistro.vn/thuc-don/#binh-thanh
Report: https://directindex.org/r/obistro.vn
Scanned: 2026-11-05 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Ơ Bistro is mostly ready for agents.
Some AI assistants are turned away by Ơ Bistro's website. It can read what Ơ Bistro offers. It finds a way to book or order directly, through ipos.

## Direct links
- Order directly: https://booking.ipos.vn/public/booking/6d06ab90-03a3-47ca-b4d8-8b0a72ba90c6 (through ipos acting for the business)

## What to fix first
- **The server turns AI crawlers away at the door.** (+6.7 points) Requests as GPTBot (http_403), ClaudeBot (http_403) were refused, but a normal browser got the page. That's usually a bot list at the host or in a firewall that the owner never chose. Ask the host to allow these user agents. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **robots.txt blocks GPTBot, ClaudeBot, Google-Extended.** (+3.7 points) These are the crawlers behind ChatGPT, Claude, Perplexity and Google's AI features. Remove the Disallow lines for them, or add explicit Allow rules. Guide: https://directindex.org/guides/robots-txt-for-ai-agents
- **No llms.txt.** (no points, but worth doing) Optional for now and cheap to add. It's a short text file that describes the business for language models. Guide: https://directindex.org/guides/llms-txt-for-a-business
- **The phone number on the site doesn't match the open map data.** The site shows 0764123123, but OpenStreetMap or Overture Maps lists +84866555157. An assistant that sees two numbers can't tell which one to trust. Fix whichever is wrong, on the site or in the map data at openstreetmap.org.

## What the site tells visitors (Measured, not scored)
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is.

## Fix kit: What to paste

robots.txt. Add these lines to /robots.txt and delete any Disallow rule that names these crawlers.

```
# Let AI assistants read the site: they send people to you; a marketplace keeps them.
# Remove any Disallow lines for these names elsewhere in this file.
