This is what I tell people: it is not that salty and I taste a bit of sweetness with it (that sort of mild sweetness, hope you know what I mean).
If I travel to Germany in the future, I would love to try Mett. That's one dish people here sometimes turn their heads at, however it sounds very nice from the descriptions.
I think more people should consider the whole "when in Rome, live as the Romans do" idea when traveling, food is a great way to appreciate a country or area.
