About the article "Eiffel Tower", section "Accommodation".

Candidate passages:
When built, the first level contained three restaurants (one French, one Russian and one Flemish) and an "Anglo-American Bar".
After the exposition closed the Flemish restaurant was converted to a 250 seat theatre.
A promenade ran around the outside.
On the third level there were laboratories for various experiments and a small apartment reserved for Gustave Eiffel to entertain guests.
This is now open to the public, complete with period decorations and lifelike models of Gustave and some guests.
The Eiffel Tower (, ) is an iron lattice tower located on the Champ de Mars in Paris.
It was named after the engineer Gustave Eiffel, whose company designed and built the tower.
Erected in 1889 as the entrance arch to the 1889 World's Fair, it was initially criticised by some of France's leading artists and intellectuals for its design, but has become both a global cultural icon of France and one of the most recognizable structures in the world.
The tower is the tallest structure in Paris and the most-visited paid monument in the world; 6.98 million people ascended it in 2011.
The tower received its 250 millionth visitor in 2010.
The tower is tall, about the same height as an 81- building.
During its construction, the Eiffel Tower surpassed the Washington Monument to assume the title of the tallest man-made structure in the world, a title it held for 41 years, until the Chrysler Building in New York City was built in 1930.
Because of the addition of the antenna atop the Eiffel Tower in 1957, it is now taller than the Chrysler Building by .
Not including broadcast antennae, it is the second-tallest structure in France, after the Millau Viaduct.
The tower has three levels for visitors, with restaurants on the first and second.
The third level observatory's upper platform is above the ground, the highest accessible to the public in the European Union.
Tickets can be purchased to ascend by stairs or lift (elevator) to the first and second levels.
The climb from ground level to the first level is over 300 steps, as is the walk from the first to the second level.
Although there are stairs to the third and highest level, these are usually closed to the public and it is generally only accessible by lift. 
The tower has two restaurants: "Le 58 tour Eiffel", on the first floors and the "Le Jules Verne", a gourmet restaurant on the second floor, with a private lift.
This restaurant has one star in the Michelin Red Guide.
It is run by the multi-Michelin star chef Alain Ducasse. 
Sauvestre contributed to the design of the Eiffel Tower, adding the decorative arches to the base, a glass pavilion to the first level and the cupola at the top.
He also chose the color of the tower.
He received the support of Gustave Eiffel who bought the rights to the patent on the design which he had filed together with Maurice Koechlin and Émile Nouguier.
He was also the head of Architecture department of Compagnie des Etablissements Eiffel 
In 1884 Nouguier and the structural engineer Maurice Koechlin, who also worked for Eiffel, came up with the idea of a large tower to act as the centrepiece of the Universal Exposition which was to be held in 1889.
The two engineers consulted Stephen Sauvestre, head of the architectural division of the Eiffel company, who added embellishments including the decorative arches of the base and the glazed pavilion on the first level.
The proposal was put before Eiffel, who approved the project, and presented it to the French Minister for Trade and Industry.
In 1884 Gustave Eiffel, Émile Nouguier and Maurice Koechlin registered a patent for the construction of pylons with heights of over 300 m. Later Gustave Eiffel bought the rights from the other two for one percent of the total earnings of the tower if it will be built.
They received around 50,000 francs.
