I was unfortunately not in Argentina, but at a wonderful restaurant in HK, the Buenos Aires Polo Club. Fantastic meat, Malbec and dulce de leech flan.
I must visit Argentina, though, as many of my sporting idols hail from there (Guillermo Vilas, Hugo Porta), and I have alway admired their mix of British style and Latin flair.
As for wearing the watch well under the cuff, HK is a troubled city these days, but thankfully wearing a nice watch is not an issue.
