CHICAGO – If you can remember the 1990s outside of childhood, you are in the glow of middle age, so congratulations. The Brown Paper Box Co. theater ensemble takes us back to those thrilling days of yesteryear with “Spike Heels,” a relationship comedy centering on the co-mingling antics of two couples, with a slight nod toward George Bernard Shaw and the play “Pygmalion” (or its musical counterpart, “My Fair Lady”).
