This was the only Norwegian phrase my grandmother would teach me.

I love how similar this sounds to "thanks for nothin"

I was hoping this meant "Thanks for mating".

A great compliment.

I visited Fleicher's Hotel in Voss, Norway for a meal with my wife. At the end I remembered to say "Takk for Maten" to the young girl waiting table. She was thrilled that the English people did this. And, of course, I was thrilled because she was thrilled... it was all very nice. Thank you Duolingo.

Ha det og takk for alle fisken

You can also just say "Takk for mat" according to my Norwegian bf.

So you would say that in a restaurant, too? I thought you would only say that if you were invited (family, friends,...).

Velbekomme.
