The room test: could five strangers hear each other?

Every place we list on the neighbourhood pages is read one way: could five people who just met settle in, hear each other, and want to stay? That kills most of the famous rooms instantly. The band room is great; it is not a first-table room. The tiny bar with the queue is great; you cannot fit five. What passes: a long table you can book-ish (we never book, but the table can), a back room, a beer hall bench, a cafe that does not flip tables at 45 minutes. Post the rooms in your suburb that pass the test. Real places only, and say WHY it works: noise, table shape, price of a first round.
