We had dinner in MAR, and by far was the best dining experience we had on the whole trip.
After a while looking at the menu, we decided to take both the tasting menu. As with most tasting menus, we had to order it both so we did. It is expensive as some reviewers have said, but food in Iceland is very very expensive, so its something you have to take on account.
The menu included a rissotto with lobster (incredible), scallops, salmon, bacalao (don't remember the translation), lamb (we preferred lamb over meat and they had no problem with it) and 3 desserts.
Everything was amazing and will visit again when in Reykjavik.
