We tried a new-ish restaurant that is, quite literally, around the corner from our house. It is an Argentinian steak house. A handful of tables indoors and 3 outdoors. The owner/server told me they (husband is the chef) opened about a year ago and that they go to the mainland once a week to get their delicious beef. We shared a couple of emanadas and grilled short ribs. Came with mashed potatoes, grilled corn and a salad. Along with 3 glasses of
their best cab, came to just over $1000 pesos before tip. Ave. 20, about 1 1/2 blocks south of 11. Give it a try. You won't be sorry.
