EATERY OBITUARIES: The restaurant business is a tough one, even if you have been in business for years. Cock of the Walk, in business for decades at 7103 Cock of the Walk Drive in Maumelle, closed Nov. 4. Lulu’s Latin Rotisserie & Grill, at 315 Bowman Road, and Mimi’s Cafe, at 11725 Chenal Parkway, part of a chain out of Dallas, have also called it quits. Agave Restaurant, a new restaurant off Interstate 30 in Benton, has also closed, apparently over a tiff with property managers about heating and airconditioning, mysaline.com reports.
