Bro's Cajun Cuisine (Nashville, TN), Greek Corner Restaurant (Cambridge, MA), The General Store (Silver Spring, MD)

This trip Guy's rolling out for some timeless traditions. In Cambridge, Massachusetts, a Greek joint where two brothers are serving the same spit-roasted lamb they loved growing up. In Nashville, Tennessee, a Cajun joint doing a classic bayou crawfish boil with house smoked sausage. And in Silver Spring, Maryland, a 19th century post office turned restaurant cranking out American standards like corndogs and chicken 'n waffles.
