Apparently the city of Buenos Aires has solved all its problems and is now closing tango venues lacking fire sprinkler systems:

El gobierno porteño clausuró una de las milongas más famosas del mundo
La milonga conocida como Sunderland, y que ahora lleva el nombre de Malena, no pudo abrir sus puertas como lo hace desde principios del siglo pasado debido a una disposición del gobierno de Mauricio Macri. [My translation:] Buenos Aires’s government shut down one of the world’s most famous milongas
The Sunderland milonga, now named Malena, could not open its doors as it had for nearly a century due to Mauricio Macri’s government ruling. The restaurant and bar operations are not closed.

The venue also hosts basketball, soccer, rollerskating and martial arts activities. They won’t be able to resume until the fire sprinkler system is fully operative.

Last month the city also shut down the Sin Rumbo milonga.

I was at Sunderland on a Saturday night, where hundreds of older local couples dressed up to dance great tango. Here are Flaco Dany and Silvina showing how it’s done:
