Why was this place not included: http://m.unionoysterhouse.com/pages/overview.html ? It claims to go back to 1826.
nice!
In Boston several other very old restaurants closed in recent times. Jacob Wirth's which was started in 1868 closed in 2018. They were apparently the first distributor for Anheuser Busch and Wirth was a founder of Narragansett beer.
