hamburg 1889
a typical PUB/RESTAURANT near the harbour where sailors , captains , longshoremen and business-people would meet .
i still remember when my dad would take me along perhaps 2-3 times a year when he had meetings with various people .
i better mention it was AFTER 1889 !

- 1938-39 more likely .

as you can see , children were quite welcome - but wouldn't be served "intoxicating" drinks !
