The number of visitors and the money they lost both ticked up at the new downtown Chicago casino in December.

But Bally’s continues underperforming the sky-high revenue expectations for the city’s only legal gaming destination.

Data released by the Illinois Gaming Board Monday show Bally’s tallied 99,832 guests at its Medinah Temple gaming facility in December — once again notching the second-highest monthly attendance of Illinois’ 15 casinos, behind only Rivers Casino in west suburban Des Plaines and its 279,106 patrons.

While Bally’s December customer count amounts to an average of 3,220 visitors per day, an 11.7% increase compared to the casino’s 2,882 daily visitors in November, it’s still less than the 3,347 daily visitors Bally’s saw during its first month of operations in September.
