Smedley's Christmas Menu and Music 1925.
The music played by the Orchestra during the meal is shown on the left and the banquet's courses are on the right.
Of note is that there is a Gelée au Vin de Champagne on the menu.
Recipes for Ris de Veau à la Pompadour also sometimes include white wine amongst the ingredients.
So by 1925 there was alcohol at Smedley's, even if it was only in the food.
