[2] The Walden Galleria comprises more than 1,600,000 square feet (150,000 m2) of retail space, with 170 stores on two levels, including a food court and a movie theater.

The mall featured a range of upscale and traditional anchors, Bonwit Teller, L.L.Berger, The Sample, AM&A's, Sibley's, JCPenney, and Sears.

Later that year, on December 14, 17-year-old Cynthia Wiggins of Buffalo was struck by a dump truck while trying to get to her first day of work in the mall's food court from a NFTA Metro bus stop on Walden Avenue.

[31] Plans were announced to expand Walden Galleria by razing the recently shuttered The Bon-Ton to make way for a wing for additional stores, anchored by a 16-screen Regal Cinemas multiplex on the upper level.

An existing exterior entrance with escalators and an elevator going up to the food court was removed and the large exterior glass wall was temporarily blocked off with the intention of creating a Barnes and Noble store in front of that space that would open up to the food court.

However, that location became Dave and Buster's instead due to complications in the construction of Barnes and Noble's proposed escalators since that particular section of the mall was built on caissons over Scajaquada Creek.

"[41] Local citizens outraged by this policy also spoke out against it, with a massive boycott against the mall organized at 12:00am on Black Friday, with over 4,000 people purportedly attending,[42] which encouraged shoppers to "steer clear" of the Walden Galleria.

[47] Regal Cinemas also announced upgrades which saw it bring 4-DX technology that immerses people in movies with moving seats, wind, rain, lights and even smells.

[49] On August 27, 2020, it was announced that department store retailer Lord & Taylor would close its traditional brick and mortar format as a direct result of the COVID-19 pandemic.

[50] Early plans envision the 99,534-square-foot (9,247-square-meter) store reconstructed into a modern space known as York Factory, a co-working sub-brand offering soft amenities such as a program delivering lunch straight to offices, bike rentals, a physical and mental wellness studio, salon services, and weekly events.

[51][52] In 2021, Walden Galleria was listed among the top 20 most visited shopping centers in America attracting over 23 million visitors from the United States and Canada.
