About the Author
I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.
This looks like a eatery of prison.
I am also very interested what renderer was used. Looks like cycles with Blender internal for volume light.
I too am interested to know what renderer was employed here. Nice picture.
Could you do a tutorial on how to get your flooring to look like that with the dirt and grime and all. I love that feel and really need to pull that off on a project I'm working on.
