Food halls are more complicated that the average observer might expect. As JLL says in a new report, they're difficult to design, build, curate and operate. Perhaps more worrisome, it adds this somber observation: With so many of them sprouting up, odds are that some will fail. JLL's new report "So You Want to Build a Food Hall" is a soup-to-nuts guide to making sure that a food hall investment is a success. It covers everything from choosing an operator, to developing a food hall brand, to appealing to a target customer base. It also provides a number of case studies of successful food halls around the US. Read more about those in our slideshow.
