In the shoebox-sized Uptown, owner Ali Mohammed casually yuks it up with customers while he prepares a steady stream of lunchtime orders. Sure, his Polish Boys and tuna melts are popular. But his four-inch-high chicken-salad sandwiches are worth the wait in line. Topped with an optional slice of tomato, the salad itself is a creamy, tasty blend of chicken, mayo, celery bits, and onion served on a choice of white, wheat, or rye bread. He'll even throw in half a giant dill pickle on the side and pack everything in a Styrofoam box, all for the princely sum of $2.95.
