In Dublin, there was a shop that mostly just sold yeast until recently: https://www.irishtimes.com/life-and-style/homes-and-property...

It always looked closed; I walked past it for a decade or so every day without realising that it was still in business.

And then there’s the top floor of Stephens Green shopping center, which mostly just contains very strange specialised shops, with no visible customers.
