There are still a couple of locations around the UK: https://location.wimpy.uk.com/

It's also going strong in South Africa: https://locations.wimpy.co.za/

Unfortunately the UK Wimpy locator just says "0 Locations found" and won't even let me browse a map to see where there might be one.

I'd be interested to try one again ( we had one in Belfast decades ago ) but they're not making it easy.

Wimpy has 61 locations in the UK as of April 2025
