Our current group always plays at someone's house. We're all adults.
Of course, sometimes we have to shift venues due to babysitters or other RW complications, but that's cool- everyone in the group has enough room and a suitable table to use.
My first ever group, though, was in the library of East Middle School of Aurora, Colorado, back in 1977, and we played after school, so we didn't have to be 100% quiet.
On rare, rare occasions- such as an ENWorld Gameday- I find myself gaming in a game shop or a pizza place or some such. But I can count all of those instances in the past 30+ years on my 2 hands.
