My lunch buddy's noodle soup (not shown; each $5.62) was similarly well-supplied, in his case with beef stew. In mine, the greens might have added more sourness, and the noodles were nothing special, but still it was a worthy bowl, based on the pork.
Outside, that taxi-call light (photo below) is for the Plaza Tower, next door. Above the awning, the tall painted-over green sign also names Kar Won at the top (out of frame); at the bottom, it reveals tracery indicating the previous tenant's business, "nails." That explains the curious split-level layout of Kar Won; I'm figuring that my buddy and I sat in the former salon area itself, a half-flight upstairs.
