Once upon a time...
a tango dancer, no - even several, who longed for a large, atmospheric hall with a parquet floor, good music and a well-stocked bar.
So they went in search, searched and searched and after some time found exactly what they were looking for! You could almost think you were in Buenos Aires. On the other hand, the name doesn't sound Spanish at all, so they decided to call the Albert Schweitzer Haus "Tangobar".
