The Ramos Mejía general hospital and the Santa Lucía ophthalmology hospital are located in southern Balvanera. Many private health-care institutions are located in Balvanera, mostly around the Faculty of Medicine complex. Among the architectural features in Balvanera are the neo-classical Congress building and the statue group in neighboring Plaza Congreso. The El Molino coffeehouse is located across the street in a building that has seen several rounds of restoration since its heyday. The café Los Angelitos in the corner of Rivadavia and Rincón was a meeting point for poets and musicians. It features a relief of angels in its façade , which is one of the landmarks of the barrio. After extensive restorations, it was reopened in 2007 , with plans to offer live tango and become a tourist landmark much like the Tortoni and Ideal cafés. Culture There are many theater and concert halls in Balvanera. The Liceo theater and the Ricardo Rojas cultural center are two of the best-known venues. For most of the 20th century, Once had a lively Yiddish theater scene; the IFT theater still stands on Boulogne Sur-Mer street, where mural paintings celebrate its rich history. Author Macedonio Fernández resided in Balvanera for most of his adult life, and held court, together with Borges, in café La Perla across Miserere Plaza ("Plaza Once"). In the 1960s, the same café was one of the birthplaces of Argentine rock, to the point that the early hit "La balsa" starts with a reference to the washroom of La Perla (in author Tanguito's version). Many actors (such as Dringue Farías) lived in Balvanera within walking distance of the theater district. In the 1980s, Cafe Einstein was a hub of alternative art, featuring acts such as Sumo. Much of the Argentine cumbia scene of the 1990s revolved around dance halls near the Once train station. North of Once station, many former warehouses have been recycled into lofts, offices, or entertainment venues. One of these, the República Cromagnon concert hall (formerly a mini-stadium and dance hall), caught fire on 30 December 2004. 194 people were killed and over 600 were injured. The street outside the venue was closed on and off for several years to serve as a memorial, severely disturbing car and bus traffic. Commerce Currently, more than 25,000 shops are registered in Balvanera, where zoning regulations favor commerce. Many apartment buildings host one or more shops at ground level.
