Manny's is a bustling, no-nonsense, combination delicatessen/diner. No tablecloths. No fine china. The menu is immense, but folks flock to Manny's for the corned beef sandwiches, arguably the best in town. The corned beef is shaved razor-thin and piled into a mountain between two slices of dark rye bread. The most favored accompaniment is a golden-brown potato pancake. Manny's is also open in the wee hours for breakfast. In business since 1942, when the area was the heart of Chicago's garment district, it now stands in the shadow of the University of Illinois at Chicago.
