A poster below, on an older thread, lamented that some South Side board favorites (Barbara Ann's, Top-Notch, Abundance Bakery) close on Sundays, and asked about options, . . .
Depending how you define South Side there are a lot of options.
Of course, there are more restaurants than you can shake a stick at in La Villita, Pilsen, Back of the Yards and Chinatown, and many of them are open Sunday. Im guessing that the middle eastern restaurants on the 63d street drag in Chicago Lawn are good bets for a Sunday.
In Hyde Park, Bonjour and Medici Bakery are open Sundays. Bonjour is a nice community place to sit outside on a warm spring day. Medici has good product, but nowhere comfortable to sit (some teetering bistro tables indoors, where you get blasted with rock music).
In the hamburger category, another good alternative to Top Notch in Bridgeport is the Ramova Grill, which in addition to its sandwich also has excellent fries.

While I am not a BJs fan, two Mississippi soul food places sitting astride one another on Ashland fit the bill for me. Johnsons has been the source of raves on the board, and my experience there has been very good. Morrisons, a cut below Johnsons overall, has a Sunday-only menu that Ive never tried: meats (oxtail and cornish hens), sides (Mississippi chili, jambalaya, black eyed peas, etc.), and dessert (bread pudding).
