I inbibed in many a 400 year old pub when I lived in England. Great places, and you can’t beat the ambience.
Same here. I found one in Cork, Ireland that was several hundred years old. Small place, family owned and run. They have to keep it in the family to keep their annual one penny lease intact.
I asked the older woman behind the bar, drawing Guiness drafts, where the men's toilet was. Pointing to the back door she said, "It's out that door and anywhere between the stoop and Dublin will serve ya."
I was in one that passed out match books that declared 'Est. 1620'. I pointed to a very old ceramic backstop, and asked the waiter if it was made in 1620.
He looked at me indignantly and declared "Of course not. We totally remodeled in 1810".
