There are plenty of names for drink that goes to this beer with whisky. "Submarine" is the name I know best. Drink is built with large/tall glass of beer in which is dropped small glass fulfilled with whisky. Idea is to watch howthe whisky glass slowly goes in to bottom of the large/tall beer glass ... like diving submarine (some use name Titanic with this drink too). Well, I use to like that drink as a youngster but ... now when my taste buds have developed and I'm more into whisky itself, I find that drink quite awful.
P.S. Only good reason for that drink that I can come up with, at least in Finland in the old days, was to get more alcohol into beer due to high taxes for beers with higher alcohol levels. With that drink you got cheaper stonger beer in the bars.
