Start with the exact branch
Restaurants with similar English names can be in different districts or belong to different businesses. Build a Korean place card from the restaurant’s official page or a Korean tourism source, then match the NAVER district, category, phone, road address and pin. Only after the branch is proven should you judge whether its reservation button or contact route is usable.
Use the foreign-visitor route when it is actually offered
NAVER’s official help documents an overseas-visitor reservation flow and its corporate notice describes passport verification for eligible foreign users. Follow the current on-screen requirements for the exact listing rather than assuming that all NAVER restaurant bookings work without a local number. Send identity or payment information only inside the confirmed checkout that requires it.
Fallback without faking a number
Check the restaurant’s official website or named contact method, followed by a global reservation service the venue recognises. If none works, choose a comparable restaurant with a visitor-supported process or ask the accommodation concierge after booking. Never use a random Korean number, another person’s identity or an unverified payment link; a reservation is not worth creating a privacy, fraud or cancellation problem.
