Think my cut off price for a good cheeseburger is $20.
One of my all time favorites when I lived in Venice Beach, Southern California was "Hinano's" down by Venice Pier. It was claimed to be a favorite of Jim Morrison of "The Doors" who lived there..fabulous, cooked on a hotplate behind the bar (which hadnt been cleaned since the 50's)by the barstaff and served with a side of jalepenos and Lay's chips...the best.
I still miss "Stanleys" on CGB (favorite of Jimmy B)but "Stout's Lookout" overlooking CGB is pretty good too..And a definite vote for "Tramonti" ,"The Sugar Mill" beach bar for a good cheesebuger for $18 with a side of fabulous fries and a billion$ view.
