Au Trou Normand (French Restaurant, First Location) [1964-????]
SCMP reported in 2003: Founded by a former French paratrooper, Bernard Vigneau, in 1964, the 60-seat restaurant was a slice of Europe in Tsim Sha Tsui.
The restaurant was located at 6 Hankow Road (probably inside the Hanchung Mansion which opened 05/1962), at least until the 1980s.
Note: In French gastronomy, the trou normand (Norman hole) is the custom that Calvados (distilled apple brandy from Normandy) is served between two courses - usually before the main course - during a break in the meal. This should improve disgestion and "create a hole in the stomach" to be able to eat more.
