It looks like there's a terrace on the ground floor near the Biwako Sosui Memorial Hall, and it seems like you can sit on the steps there.
Also, it seems that chairs are set up when the Sosui Cafe is open for a limited time. Maybe chairs are set up all year round?

This area is bustling with people because it's near the Keage Incline and Suikou-kaku, remnants of the Biwako Sosui, as well as Nanzen-ji Temple and Kyoto City Zoo.
