These first three pictures were sent in by atmann in 2007. He notes that the name of this bar means "clutch" in English, which is consistent with Kuplung's automotive theme.
Kuplung is one of Budapest's "ruin bars", which are bars located in rundown buildings formerly occupied by other business, in this case an automotive repair shop.
This last photo from Kuplung was taken a full 10 years later by a member of Urinal Dot Net staff. It seems like a lot has changed at Kuplung in the meantime.
