Probably too late for OP, but for Sunday morning in Bridgeport, I highly recommend the Healthy Food Lithuanian Restaurant at 3236 S. Halsted. Family run, fresh ingredients. I've gone once every year or two for the last twenty years - some ethnic favorites have fallen off the menu for a more generic fare, but the Blynai (Thick Crepes) or - when they have it - the roast duck are great.
