It was named after Pioneer Market , a now-defunct small chain of supermarkets in Los Angeles . The original location in Echo Park was located next to the 1980s-era Pioneer Market ( the original 1932 market was razed in the 1980s due to the Sylmar earthquake ) at Echo Park Avenue and Sunset Boulevard , which was replaced by a Walgreens Pharmacy in 2004 . Due to considerable redevelopment activity in the neighborhood , Pioneer Take Out was shut down in March 2009 and replaced by a Little Caesar 's Pizza the following year . During the 1980s , Los Angeles Lakers announcer Chick Hearn and former football player O.J. Simpson advertised for the restaurant
