One advantage of UD is that the cabin crew - with relatively few passengers to look after, many of which will be regulars - can read the passengers quite well. But just ping away if you don't want to untangle headphones and what not. Since it's quite a small area a crew member may be visible anyway and a polite hand wave may do the necessary. The obvious thing to do though, as the dessert / cheese is cleared away, is ask for a drink at that point, port is a common request.

The one thing to perhaps slightly bear in mind, is that there is bit of downtime and a chance of a cup of tea for the crew after the meal is served and Club Kitchen put out (mostly downstairs, though there may be a few things on the ledge at the top of the stairs). They will typically have boarded 60 minutes before you and will normally have been on the go - getting to the airport, through security, on to the aircraft, prepping up - with only a short break during take off. So if you want to be unnecessarily considerate to the crew either get your drink with the tray clear-up or leave it perhaps 45 minutes. But you need a drink, you need a drink!
