At DAK, the Safari Amber is quite tasty, everything else is the standard stuff you'd find anywhere. The Imperial Sampler at Rose and Crown in the UK is quite fun, they give you Bass, Harp, Stella, Boddington's, and Guinness and tell you different ways that you can mix them together. In Japan, Kirin Ichiban is quite good, as is Bohemia in Mexico, and pretty much everything (Lowenbrau et al) in Germany is great.
