Attention shoppers: Simon Property Group, Inc. is promising a "major announcement" about Southdale Center on Thursday. Rennovation work, including construction of the new food court, is already underway -- read all about it -- so I'm thinking it's time to reveal some new tenants to replace the many lost over the last few years. Here's hoping Old Navy is not Southdale's idea of "major." The announcement will take place at 2 p.m. Thursday, May 24 in Center Court. Edina Mayor Jim Hovland, Southdale Center Manager Laurie Vandalen and representatives from Krauss Anderson construction plan to be in attendance.
