One of four locations of this local sub shop chain, which originally opened in 1971 on Clark Street in Rogers Park, this spot offers homemade soups and chili in addition to crispy bread sandwiches. Warm and cold specialty sandwiches include Italian beef; the ham, salami, egg, cheese and pineapple sauce-topped South Sea; and the liverwurst, muenster cheese, salami, egg and sauerkraut-topped Conqueror. It also offers catering. Don't ask what's in the secret sauce; Nemo's won't tell you, but you can buy it in a bottle.
