Most of my gaming is done on PC with a standard desk and office chair setup, I used to have my own 'man cave' which was home to that, a 32" TV and a sofabed for when guests stay over, but we've got my girlfriends teenage brother living with us for at least the next year so the PC is in my bedroom while he has the man cave as his bedroom.

I used to play console games on the 32" TV usually, but the aforementioned teenager currently has use of that as well as my Xbox 360 as I barely play it. Currently I use the 42" one in the living room but I don't have a chance to do that as much as I'd like to due to it being in use by other family members most of the time they're home.

I don't eat while gaming but I always have some sort of beverage nearby.
