From own experience during the test phase this works a bit different: in some lounges they prepare a cordoned-off area where they put a couple of drinks and some nibbles on a table. In some outstations they sometimes have a little private room where they set you up with a bottle of champagne and some canapes (had that in BOS once and in one other station, don't remember which, both times flying with family, so it was nice to be set up in the private room).

But take this with a grain of salt, (i) this was the test phase of that PA service, (ii) which we don't have confirmation will be part of Ultimate, even if it sounds like it.
