The Downtown Mobile Alliance Annual Luncheon will be held on September 20 at The Battle House Renaissance Mobile Hotel & Spa in Mobile. The perennially sold-out event will see the city’s business, civic and elected leaders to celebrate Downtown Mobile’s continued revitalization. The nonprofit says that keynote speaker Mitchell Silver is “a celebrated urban planner and placemaker who served as Commissioner of Parks for New York City. The program also includes an update on the state of downtown.” The event begins with music and libations at 11 a.m., with the program starting at noon. Tickets are $85 per person and $800 for a table of 10 for members and $100 per person for nonmembers.
