The neighborhood of Puerto Madero is a lovely area for laid-back walks at sundown. After you’ve taken enough sunset selfies to make your travel partner swear off being seen with you at dusk, head straight to Siga La Vaca and look for the cow statues at the entrance—the name of the restaurant literally translates to “follow the cow.” Go for the grilled all-you-can-eat steak, which costs around $15 and includes chorizo, grilled steer chitterlings, and lamb sweetbreads. There’s also a solid salad and dessert bar, too.
