# Klub 21: Agent-Direct Score D (53.8%) Site: http://21klub.cz/ Report: https://directindex.org/r/21klub.cz Scanned: 2026-10-20 (Provisional, with the action test and the assistant citation check still to come. The hatched part of the bar isn't measured yet.) Klub 21 is hard for agents to use. An AI assistant can open Klub 21's website. It can't find a menu or price list, so it answers from other sites. It finds a way to book or order directly, through Tableo. ## Direct links - Book directly: https://app.tableo.com/r/~sfY5RP (through tableo acting for the business) - Phone: +420731704055 - Address: Římská 419/21, 120 00, Praha ## Nearby, also direct Places near Klub 21 that take a booking or an order on their own website, with no marketplace in between. - Dolcemente (90 m): https://directindex.org/r/dolcemente-vinohrady.cz ## What to fix first - **No structured data for the business.** (+15 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 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 - **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 ## 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 Prague, 31% 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. ```html ``` llms.txt. Save as /llms.txt at the root of the site. ``` # Klub 21 > local business in Římská 419/21, 120 00, Praha, Prague cafes and bars.
