The Seven Stars has been a pub since at least 1760 and has the distinction of being the place where Thomas Clarkson gathered evidence of the slave trade during the 1780s abolitionist campaign, the landlord helped him, and the pub's history is genuinely significant. It is also, by modern standards, a perfectly preserved pre-gentrification Bristol pub.
No cocktails, no exposed filament bulbs, no food beyond crisps. Good real ale, a room that has changed relatively little in decades, and a clientele that has no interest in being noticed. Find it before it changes.
