North Texas heat doesn’t take a season off, and Rita’s Italian Ice is building its whole DFW strategy around that fact. The chain opens its first North Richland Hills shop on July 1, a drive-thru location at 8900 N Tarrant Pkwy, and it won’t be the last. Three more DFW shops are already under construction, in Flower Mound, Carrollton, and Farmers Branch, the company’s biggest single push into one metro area in years.
