El Palacio de la Papa Frita
No frills doesn't mean no charm at this longtime porteño favorite. Steaks, pastas, and salads are the draw, but don't miss the papas soufflés, meaning puffed-up french fries. If you want to go full-tilt local style, order them à la provençal and they'll arrive at your table tossed with minced garlic and parsley. After all, this place and the other three branches around town (Palermo, Recoleta, and another in Centro) aren't called the Palace of the French Fry for no reason.
