in which theater in buenos aires did spectators once have to bring their own chairs?

The answer is "El Coliseo"

The Teatro Coliseo is a traditional and ancient Argentine theater, located in Buenos Aires, which is located in the Retiro neighborhood (Buenos Aires), street: Marcelo T. de Alvear 1125, opposite the Plaza Libertad. The history of the theater is divided into several stages, due to the remodeling and relocation of the theater. The first stage extended between its inauguration in 1804 - even in colonial times - in front of the Church of La Merced and 1834; the second stage extended from the remodeling of 1834 and the demolition of 1873, when it was known as the Coliseo Argentino or Teatro Argentino; the third stage extended from its reconstruction in front of the Plaza Libertad in 1905 until its closure in 1937; and the fourth stage extends from the last remodeling and slight relocation, to the present.

The stalls contained approximately 250 seats; long, very narrow benches divided by arms, formed the lunettes, covered with a small cushion covered with corduroy. The general ticket was worth ten cents and the lunches fifteen; costing something less when taken by season, which was about ten features. The outline of the plateaus in the form of horseshoe, was formed by 20 or 25 low boxes, that cost a weight and other so many high ones, of three pesos by function. In each one, there were approximately six seats, but the public had to carry chairs from their home or rent them to the theater company.
