## What to fix first
- **The site turns away every visitor that isn't a browser, AI agents included.** (+25 points) A plain fetch was refused (http_429). Only a real browser got the page. Every AI crawler and agent gets turned away the same way, so Reachable scores 0 and the rest is measured on the page as the browser rendered it. Ask the host to let the AI user agents through. Guide: https://directindex.org/guides/blocking-ai-crawlers-without-knowing
- **No structured data for the business.** (+14 points) Add schema.org JSON-LD for the business (CafeOrCoffeeShop, BarOrPub or the closest type, with name, address, telephone and openingHoursSpecification, plus servesCuisine). Every assistant reads this block first, and the fix kit below has it filled in. Guide: https://directindex.org/guides/structured-data-restaurant
- **No booking or ordering link on the website.** (+13 points) There's only a phone number or WhatsApp, and agents can't use those yet. If you take bookings or orders through a platform, link to it from the site so agents can find it. Add a booking or ordering page. Guide: https://directindex.org/guides/book-direct-on-your-own-website

## 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. In Seoul, 12% of comparable sites declare one.

## Fix kit: What to paste

Structured data (JSON-LD). Paste it as one block in the page's head, or in the builder's custom code box. Change anything that's wrong.

## Already right

- **Menu or price list is an HTML page.** Agents can read the items and prices.
