This location was part of a Chicago-based chain of Pago Pago restaurants which once had 5 locations, now all long gone.
The five included 227 W. Jackson, 126 N. Wells St., 316 S. Wabash Ave., Schiller Park, and Wheeling.
The mural advertisement on the side of the South Wabash location's brick building in Chicago lasted for many years after its close and is the only photo from any of these locations available.
The building and mural sign was demolished around 2010.
We know that this address hosted the Epicurean Restaurant (Hungarian food) from 1966 and into the 70s. So, the South Wabash Pago Pago must have been open, serving Chinese food and Polynesian drinks, from the mid 70s until its close, perhaps as late as the mid 90s.
