Night Market is a recent phenomena in Philadelphia but it isn’t the first food festival the city has ever seen. As this photo from 1983 demonstrates, the rain couldn’t dampen the crowds who attended the Philadelphia Restaurant Festival on the Benjamin Franklin Parkway.
Found a little more about the Restaurant Festival in an old Associated Press article.
75 restaurants will cater to more budget-minded food lovers at the Restaurant Festival, where 250,000 people are expected to feed their fancies on treats ranging from duck galantine to carrot cake for $4 or less.
The festival, discontinued in 1978 because of a lack of interest, was revived last year as part of the city's tricentennial celebration
