Here we have a man cave that really leaned hard in its thematic approach. We have a very cook knight theme here, replete with swords of all kinds. I would even go so far to say that this is a fantasy themed man cave. Now, one of the things that I think would be great for this space would be for tabletop gaming and such. You could also use it as a movie watching space for sci-fi and fantasy fans. In any case, if you are designing a man cave, it can really look cool if you make the design revolve around your own personal passions and hobbies.
