Where to find refuge from the extreme heat in Austin this summer

I like going to movie theaters to watch a movie, AC is always blasting

Northcross Mall for some cheap food at Furr's Cafeteria, some ice-skating, and then a movie.....wait, no, that's all dead and gone......Maybe, Highland Mall...nope, that's ACC now.....uhhh.....well, there's Einstein's Arcade on the Drag where we can fight with tanks in "Tokyo Wars"....scratch that.......Mr. Gatti's Pizza on MLK with a pitcher of beer and infinite cinnamon sticks....negative, 'cuz Chicken Jesus took that over......

I guess I am all out of ideas. Wait a minute, is it against the law to set up a tent inside the Google building?
