Tango Sur

Things to know when planning a trip to this Argentine grill: You will wait for a table, and when it’s time to order, it’s best to keep it simple. Start with a plate of empanadas to share, then order a perfectly seared steak to dunk in the house chimichurri sauce and finish with the flan. Bring along that bottle of big red wine you’ve been holding on to, drink it with your slab of beef, sit outside on the sidewalk and enjoy the live Latin guitar—is life really always this sweet in Buenos Aires?
