I don't know about that particular restaurant but I found these recipes for white wine cream soup on the internet. If you describe the soup more, I'll keep searching.

CREAM WINE SOUP

Put one cup of white wine and one-half cup of cold water on to boil, add a few pieces of stick cinnamon and seven lumps of cut loaf sugar; while boiling scald a cup of sweet cream in double boiler. Have ready the well-beaten yolks of two eggs, pour over this the hot cream, stirring all the time, then pour in the boiling wine, being careful to stir well or it will curdle. Very nice for invalids. Can be eaten hot or cold.
