Rather then append to the BYOB thread a little down, I'm starting anew, since this is an issue I've been meaning to post on for a while. I went to Tango Sur for the first time a couple months ago, and was a bit confused by the two steak menus.
On the regular menu, right side were several inexpensive selections ($10-13), not your typical ribeye, filet, strip, etc.--what I presumed to be Argentine cuts, and which I had eagerly been anticipating. On the paper insert "specials" sheet, were more traditional cuts at a higher price ($18-20).
I queried the waiter, who not surprisingly urged the higher-priced cuts, but also said that they were Argentine beef while the others were American beef. I wanted to ask whether they were grass- or grain-fed, but my wife (who gets a bit embarassed when I'm overly inquisitive about menu selections) had warned me in advance not to do so.
Anyway, we both ordered the more expensive, traditional selections and were a little disappointed. The steaks were good, but they were far enough below steakhouse standards, that the price-to-quality ratio between Tango Sur and many other places seemed similar.
Should we have ordered the Argentine, cheaper cuts? Did the waiter correctly distinguish the Argentine and American beef? And does anyone know, as zorro asked, which selections, if any, are grass-fed?
