Clark walks through the doors of the cafe wearing a tuxedo. There was a formal party at the Daily Planet, but Clark felt the need for some fresh air (ironic considering who he was underneath the tuxedo) and somehow he ended up here.
Still wanting that fresh air, he went outside and sat on a bench near an outdoor fireplace. It wasn't lit yet, so he uses his heat vision to light it.
With a content sigh, he leans back and looks up at the night sky.
