Looking for a space in downtown San Francisco to have a presentation

[Guest guest]

Hello,

 

I am organizing a Walk for Farm Animals, benefiting Farm Sanctuary, and I need

to find a space in downtown San Francisco that can accommodate 150-200 people

and has some sort of stage for the speakers.

 

This is a non-profit event, so we are looking for space that won't cost

anything, or very little.

 

The space would preferably be outside!

 

We will have a one hour presentation followed by a walk.

 

Thanks for any help/advice you can give me.
