Probably the best steak I have had was from Jeff Ruby's The Precinct in Cincinnati.....I'm still not sure if it is "Dry-aged" from the description of their meat, I'll have to start paying attention to that as you have piqued my interest!
"Jeff Ruby's beef is personally chosen for his steakhouses, exclusively, by one person. Then the beef is aged to his very demanding specifications and, unlike the national chain upscale steakhouses, the steaks are butchered here on the premises.
