Even if the government hasn't ordered them closed, it might be worth avoiding them as an individual. Especially if your government is one that hasn't been super on point with responding to the pandemic (so maybe not germany so much since they seem to be doing a reasonable ok job compared to some other areas). If there's significant undertesting etc in your area, the government will not have a full enough picture of the situation to be making accurate reccomendations about what should be open and closed.
