On the corner of Josephine inside the Avenue Plaza Hotel, Mr. John’s is a classic New Orleans steakhouse pouring its all-USDA-Prime cuts to the table sizzling in butter. Round out the meal with à la carte sides like creamed spinach or the andouille-and-crawfish “Freddie” mac and cheese, and lobster or crab cake if you are feeling it. A polished, old-school room right on the streetcar line.
