I have never had that before, sounds neat!

See that is the trouble with Guiness, and perhaps other thicker beers. One pub I have been to has poured an excellent pint of Guiness. Some are so-so, and then there are the few that treat it's like a PBR or something. I think pouring and drinking Guiness is a bit of an art-form, perhaps another reason it is treasured.
