The drawing below is from Gustave Eiffel's book describing the tower that bears his name. There are 53 of them in total.
XXIX. French restaurant and Russian restaurant
The XXIX technical plate describing the Eiffel Tower is very interesting because it shows us elements that have disappeared today. These are the two restaurants on the 1st floor, the French restaurant and the Russian restaurant. There is always a restaurant at the Eiffel Tower, the Jules Verne, but it is not the same as at that time. The plans show in particular the similar facades to each other, with relatively few ribs. It's more of a general plan than anything else.
