# Tacos El Tucán: Agent-Direct Score D (45.7%) Site: http://tacoseltucan.com Report: https://directindex.org/r/tacoseltucan.com 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.) Tacos El Tucán is hard for agents to use. Some AI assistants are turned away by Tacos El Tucán'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 Toast. ## Direct links - Order directly: http://toasttab.com/local/order/tacos-el-tucan-nro-15-harbor-st (through toast acting for the business) - Address: 3600 16th St, 94114, San Francisco ## Nearby, also direct Places near Tacos El Tucán that take a booking or an order on their own website, with no marketplace in between. - Super Duper Burgers (30 m): https://directindex.org/r/superduperburgers.com - La Méditerranée (30 m): https://directindex.org/r/lamednoe.com - Taco Boys (60 m): https://directindex.org/r/tacoboys.net - Starbelly (90 m): https://directindex.org/r/starbellysf.com - Canela Bistro Bar (110 m): https://directindex.org/r/canelasf.com ## What to fix first - **No structured data for the business.** (+15 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 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 server turns AI crawlers away at the door.** (+3.3 points) Requests as ClaudeBot (challenge:attention required) 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 - **Almost no text without JavaScript.** (+2 points) Crawlers that don't run scripts see an empty page. Put the menu, hours and address in plain HTML. Guide: https://directindex.org/guides/website-blank-without-javascript - **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 ## 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. ``` # Tacos El Tucán > local business (taco) in 3600 16th St, 94114, San Francisco, San Francisco. ## Book or order directly - Order: http://toasttab.com/local/order/tacos-el-tucan-nro-15-harbor-st (through toast acting for the business) ## About - Website: http://tacoseltucan.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 main AI user agents. - **Ordering through toast on your own domain.** There's no marketplace commission, and the customer stays yours. - **Toast works with agents through its partners.** Toast's guest terms could not be read on 2026-10-15 (bot challenge); since August 2026 Google's Ask Maps completes orders at Toast restaurants through Toast Local under the UCP for Food standard.
