Gáttaþefur - has a masochistic streak, he just stand by the door and sniffs, and sniffs.
If you're not good, he might sniff up all the good smells from the christmas meal.
Of course in our frantic state, we burned the (leftover) pizza, so he can sniff all he wants.
We went Herwig's Austrian Bistro - Herwig's - where bacon is an herb!.
There I learned two things: they now have chocolate covered bacon for dessert, and if you're the last customers, and they have a lot of sachertore left, the portions get bigger.
Much bigger.
