One facade missing from the walking tour of Penn Ave.---submitted by a user on a SkyscraperPage Forum---is one with a rather Korean look to it. Kim's Coffee Shop, at 5447 Penn Ave., was a Vietnamese place, though, run by immigrant Mai Hong Khuu until her cancer diagnosis and death in 2006.
The walls and the eaves resemble those on hanok (한옥), traditional Korean houses. The restaurant space and the house above it was purchased by the Pittsburgh Glass Center in 2012.
