At my house, we play at my dinner table, sitting in comfy chairs. I use a screen only when I have a map or something similar to hide. We usually start out with music at low volume, then once are deeply into the game, we all forget about it and usually no one even notices when that first CD has run out.
Another group I play in hunches on sofas and armchairs around a small, low coffee table. Requires more juggling around of drinks, maps, dice and stuff than playing at a larger table, but is quite comfortable as well.
Yet another group I know plays in a studio flat without decent seating. Players lounge on the bed or carpet. A huge world map is spread out between them on the floor.
All these environments are great in their own way.
On the other hand, I've played in a group that meets in a civic hall, sharing a huge room with three or four other groups playing other game systems. Voices tend to echo in there, and there are always lots of additional empty tables and chairs around. People wander between tables to chat, lend and discuss books and movies, and there's more table talk than actual gaming on at the table on an average night.
Heck.
I'll take any gaming environment in a private home over that.
