Ive been very fortunate and blessed to have eaten at many of the top rated and best known steak houses in the world. Peter Lugers in NY, the original mortons in Chicago, Margaret in Sydney, etc. For me, overall the best steaks are in Buenos Aires. There are at least a dozen steakhouses there that I'd personally put in the top 25 in the world in terms of quality of the meal and quality of the ambiance. Then factor in that they are some of the most affordable anywhere on the planet, and they get very hard to beat.
If anyone is headed to Argentina for a hunt this year, dont screw yourself out of an opportunity to have a meal at Estillo Campo. The last time I ate there the meal was beyond divine. The service was impecable, and I think the tab came to about $30 a person with all of us eating appetisers, sharing a bottle of wine, eating steaks, a couple of sides, desert, and an after dinner coffee.
