LARGE event locations???? (Mexico City)

Hi Everyone,

I am in the beginning stages of organizing a Protected content Protected content event. I am searching for an event venue that can hold this number of people. The few that I already knew about are not available for the dates I'd like to host the event. The event is a fashion show and after-party in support of gay rights & freedoms in Mexico. Any ideas for an event venue?

Thanks!
