If we're gaming at the home of three of my four players (which is the norm), we game in their kitchen. If we're gaming at my house, we play in the dining room (if everyone's there - bigger table) or in the kitchen (if there are only three players that session).
In previous houses, we used to play in my library/den, or sometimes the living room or family room.
That was me making fun of some other set of polls (there's like 50 of them or something) which ask potentially quite involved questions and have only those two answers (which in my opinion makes them irrelevant since there's hardly any basis for judging what "yes" and "no" mean in those cases).
