The Backstreet Boy’s were back Friday night in Chicago and started it with a Mexican dinner at city’s newest hotspot, Barrio. Three of the five members of the hit boy band, Howie D, A.J. McLean and Nick Carter were in town as they were performing for Florida Georgia Line’s Smooth Tour. The group of eight, which included wives and friends, dined on Chef Katsuji Tanabe’s Mexican fare including queso fundido and of course his tacos. As Chef Tanabe was on hand in the kitchen, he made a point to stop by and say, “Hi” to the band members before they made their way out for the night.
