Hy-Vee Inc. opened its second store in Ankeny on Tuesday. The 93,000-square-foot store at 2510 S.W. State St. is similar in design and layout to the store that Hy-Vee opened last month in Waukee, officials said in a release. The Prairie Trail Hy-Vee represents an $18 million investment in the Ankeny economy and the addition of 640 jobs, making it the company's largest store in terms of employment. The store features Hy-Vee's new Market Grille restaurant and café, a full-service dining experience that offers customers the option of ordering from a menu and enjoying wine or beer with their meals. The West Des Moines-based retailer plans to open four more stores this fiscal year in Nebraska, Wisconsin and Illinois and begin construction on several more as part of a $300 million capital improvement plan.
