Help with the name of a Venue

The “Cosa Nostra MX” is a venue in Mexico City the last friday I've seen alive to Cattle Decapitation, but the correct name of the venue is “Cosa Nostra MX” and in the page the name is wrong like “La Cosa Nostra MX”, the word “La” is no a correct word in the name of the venue.

This is the venue:

This is the facebook page of the venue, with the REAL NAME: https://www.facebook.com/Cosa-Nostra-MX-1662603064016155/

Thanks
