How do you translate Infoabend in English?
linguee translates it as "information evening" which sounds odd to me
and LEO doesn't even have an entry for it.
and "open house" is another kind of event, and is translated as "Tag der offenen Tür".
An Infoabend is usually just a more casual event usually with a presentation and time afterwards to ask questions and meet the people at a clinic, company, organization, etc.
