The sights and sounds of New Orleans reverberated through Lexington this Tuesday in celebration of Mardi Gras. The “Cajun and Creole joint” Bourbon n’ Toulouse catered to a line spilling out into the sidewalk of Euclid Ave., as Lexington residents waited to order a platters of crawfish. Before entering the shoulder-to-shoulder space, local musicians played the New Orleans classic “The Saints Go Marching In,” and dancers performed the samba to entertain residents waiting in line.
