Nope I don't have one, I don't have the space for it. I'm thinking once we inherit the house from my in laws I am going to make one in the basement, which is where my wife and I are staying in now.
I don't have one but my friend has a little man cave in his garage. It has a few neon lamps and a mini fridge full of beverages. It is the ideal mini getaway after hard working days.
