Iceberg: Snorri's Restaurant

pg 120

If Snorri's Restaurant in Reykjavik could be picked up and placed down in any of the epicurean cities of the world...

There's a Snorri's Guesthouse in Reykhavik, but not a restauraunt. (Though of course there might have been one 30 years ago!)

The restaurant was perhaps named after a famous Icelandic person:
Snorri Þorgrímsson or Snorri Goði (; 963-1031) was a prominent chieftain in Western Iceland, who featured in a number of Icelandic sagas. The main source of his life is the Eyrbyggja saga, in which he is the main character, although he also figures prominently in Njál's saga and the Laxdæla saga. Snorri was the nephew of Gísli Súrsson, the hero of Gísla saga, while his son Halldórr was the subject of two tales detailing Halldórr's service in the retinue of the Norwegian king Haraldr Sigurðarson.
Eyrbyggja Saga says of him "He was a very shrewd man with unusual foresight, a long memory and a taste for vengeance. To his friends he gave good counsel, but his enemies learned to fear the advice he gave."
Njál's saga says of him "Snorri was reckoned the wisest man in Iceland, not counting those who were prescient"

Its one great hall, with open kitchen and earthen ovens only a few feet from the dining area, was designed in the Viking condition.

The Vikings (from Old Norse víkingr) were the Norse explorers, warriors, merchants, and pirates who raided, traded, explored and settled in wide areas of Europe, Asia and the North Atlantic islands from the late 8th to the mid-11th century.
These Norsemen used their famed longships to travel as far east as Constantinople and the Volga River in Russia, and as far west as Iceland, Greenland, and Newfoundland, and as far south as Nekor. This period of Viking expansion – known as the Viking Age – forms a major part of the medieval history of Scandinavia, Great Britain, Ireland and the rest of Medieval Europe.
Popular conceptions of the Vikings often differ from the complex picture that emerges from archaeology and written sources. A romanticised picture of Vikings as Germanic noble savages began to take root in the 18th century, and this developed and became widely propagated during the 19th-century Viking revival. The received views of the Vikings as violent brutes or intrepid adventurers owe much to the modern Viking myth which had taken shape by the early 20th century. Current popular representations are typically highly clichéd, presenting the Vikings as familiar caricatures

"I took a walk in the Tjarnargardar Gardens and lost track of time."

 This sounds like it should be an actual place, but there is no mention of Tjarnargardar Gardens on the internet at all!
