The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
The source gives the month only: "It was opened in March 1998 under the management of Chef Andoni Aduriz." A month-only date sits on that month's last day.
The MICHELIN Guide's own entry, which states "a Two Stars: Excellent cooking restaurant in the 2026 MICHELIN Guide España" - the rating this pin records, and the reason its address reads Errenteria while the coordinates fall in Astigarraga.
The World's 50 Best (Restaurant magazine) is the body behind the ranking the pin cites for Mugaritz's standing.[1]
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
