# Glückstein: Agent-Direct Score D (43.1%)

Site: https://www.restaurantglueckstein.de/
Report: https://directindex.org/r/restaurantglueckstein.de
Scanned: 2026-10-24 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.)
Glückstein is hard for agents to use.
An AI assistant can open Glückstein's website. It can't find a menu or price list, so it answers from other sites. It finds a phone number, but no link to book or order online.

## Direct links
- Phone: +49 621 437151625
- Address: Lindenhofstraße 62
- Hours, from OpenStreetMap: Mon–Fri 11:30–22:00; Sat 17:30–22:00; Sun closed
- Outdoor seating (OpenStreetMap)

## Nearby, also direct

## 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). 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
- **No menu or price list found.** (+7 points) Agents answer 'what do they offer?' from marketplaces instead. Add a page with the menu or price list and link to it from the homepage. Guide: https://directindex.org/guides/menu-pdf-ai
- **The phone number on the site doesn't match the open map data.** The site shows 0621 43751625, but OpenStreetMap or Overture Maps lists +49 621 437151625. 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)
- **The footer says © 2023.** Visitors and assistants may read that year as the last time anyone looked after the site.
- **No English version declared.** Visitors from abroad, and assistants answering in English, read the page as it is.

## 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.
