Hole in the wall? This feels like an "in the know" locals place. It was recommended to me by one. The neighborhood has been battered by the economic downturn and seen better days, and you don't expect tourists to flock here, as their resorts are away from here. The burger, simply seared on a flat plate (that appears not to have been cleaned in 50 years) gives the beef the perfect char that seals in the juice. The marinade in red wine gives the beef an edge up in flavor. Unique. Also like the wet fries. Airport close; worthy of a side trip.
