When we were last there, these new bars weren't open, so there was no cleanup going on there at that time. We talked with Karl at Kakao, and he's the one that told us that they cleaned it up each morning before they opened, and by 10 AM it was back.
As far as the personal chairs and umbrellas are concerned, I doubt there will be any room for those once all the establishments are up and running. That area has always been tightly packed.
