Follow up on my last night in BA. Went back to Desnivel for lunch. Tried to order the flank steak but they didn't have any. Ended up getting beef de chorizo again this time rare. Sadly it was just a little less over cooked than the first time, nowhere near rare and didn't even taste as good as last time.
For dinner I went to La Brigada. I ordered cured ham (prosciutto) for appetizer. It was a bit frozen, otherwise ok. For steak I wanted to order the skirt steak but they were out so I went with the ribeye rare. Finally I received a perfectly cooked steak in BA. It was a bit on the salty side but it was really good. It was a very tender thick lean cut. Definitely doesn't look like what I am used to back home and it did look a bit like the ribeye I got at the Sheraton a few days earlier but in this case it was cooked right. The one thing I read in some of the reviews for La Brigada is that they can cut their meat with a spoon. Well that seems to be their shtick and I guess that's not a bad thing. The table next to me had a party of six. They all ordered the same thing, I think it was the fillet so a large piece of meat was brought over to their table and cut into 6 slices table side with a spoon. Funny thing about it was that 4-5 of the 6 ended up sending their steak back to get it cooked further. From where I was sitting it looked like they were initially served a really nice bloody medium rare.
I think if/when I come back to BA I'll start with La Brigada and try some of their other cuts. While not the best steak I've ever had it was very good.
@Flying Machine Sadly didn't get a chance to go to go to Parrilla Pena but wish I did instead of going to Desnivel for the second time but was in the area of Desnivel already during lunch. Thanks for your recommendation.
