The hatched part of the bar isn't measured yet.) I SSHIN Izakaya is partly visible to agents. An AI assistant can open I SSHIN Izakaya'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 cukcuk. ## Direct links - Order directly: https://isshin.cukcuk.vn/order-online/ (through cukcuk acting for the business) - Phone: +8418009030 - Address: 208 Nguyễn Hữu Cảnh, Phường 22, Quận Bình Thạnh, Hồ Chí Minh, Việt Nam, 72324, Quận Bình Thạnh - Languages: Vietnamese, English ## Nearby, also direct Places near I SSHIN Izakaya that take a booking or an order on their own website, with no marketplace in between. - Kohaku Sashimi & Yakiniku (210 m): https://directindex.org/r/sol.com.vn - Oriental Pearl Restaurant (230 m): https://directindex.org/r/orientalpearlsaigon.com - Truffle (240 m): https://directindex.org/r/the-truffle.com ## 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).
