This is a really subjective question - some will love the taste of beer, others will hate it. Same goes for wine, vodka with a mixer etc.
If you're talking about a "starter" drink and something sweeter, cocktails aren't a bad shout as most have a lot of soft drinks to disguise the taste. Cider (Strongbow) isn't bad either.
If you're talking shots, jagerbombs don't taste too bad and can get you wasted pretty quickly.
