Parnell's (also referred to in the diaries as simply “Parnell”) was a small diner or restaurant at 528 W. 63rd Street. It was a regular gathering place for Dorothy and Louise and their friends, especially for their great Cherry Cokes, served from a fountain. It had four or five booths. A fellow named Jim was the owner. Jim once threw Dot, Sis and two of their friends out of the restaurant for lingering too long over only a couple of Cokes.
I have been unable to locate any information about Parnell's besides a listing in the 1945 Chicago telephone book (WEntworth 4903). It may have became the Green Lantern restaurant at a later date. The location is now occupied by townhomes.
Parnell's was about a half-block north of the L tracks (see photos) and just east of the railroad tracks (now used by the Metra commuter line) and the now-demolished train station, on the north side of 63rd Street. It was an easy three blocks' walk south from Dot's house.
