Well, maybe you get some different stuff on Iceland or sonething, because the general concensus around here is that they're very similar. But I have to agree with you on grolsch, it's definitely a very good beer (and the bottles are just so cool
).
And if tuborg is the only alcoholic drink that you didn't like, I'm guessing you never tried stroh rum. That has to be the nastiest stuff I've ever tasted, and it has an alcohol percentage of 80.
