Fodor's Expert Review Puesto La Lechuza

Your first difficult decision at this waterfront eatery is where to sit: at a breezy outside table overlooking the river, or in the rustic yellow-painted interior hung with historic pictures of gauchos. Let gaucho-diet principles guide your order—go for the beef asado or vacío (on and off the bone, respectively), slow-cooked over hot coals. The little stage where folky guitar players perform in the evenings might look touristy, but locals love the singsong here as much as visitors. Reservations are essential on the weekend .
