I was in 5J this past week and despite there came a point when passengers and crew clearly became aware that they were disruptive with their conversations, is still snag a seat near the galley. But be warned of course, at some people the awake folks will want to "talk" and will head to the galley.

Im on this flight nearly at a monthly rate so there are time when I've not been bothered when seated from 3-7 in J. But one of the crew members on this last flight said that the Y galley tends to be worst since there are more people in the rear looking for food and conversations.
