Time Out says
An authentic slice of old Glasgow
Between Trongate and the Clyde, the Scotia claims a heritage going back to the 18th century and for major chunks of the 19th and 20th centuries it sat next to a theatre that's now long gone. It may not look like much from the outside but this pub can make a genuine claim to be the city's oldest. It has wood paneling throughout, old photos around the walls, a basic bar menu, folk music at the weekends, cask ale on draught – Ossian from Perthshire, perhaps – and always a special offer on a single malt whisky.
