Its taste is much more bolder and stronger than 'Guiness Draught'.
I can't say which one is better, but for me, 'Guiness Draught' is rubbish.
I do like 'Guiness Foreign Extra Stout'... but, I can't find it at Seoul???
All Guiness beer at CVS, pub, taverns and restaurant at Seoul is 'Guiness Draught'.
Where can I find it? If anyone knows it, please let me know....
