When you first walk up to Jimmy’s Famous Heroes, you’ll wonder what could possibly smell so good. If you ask, the people behind the counter will let you in on the secret of their chicken cutlets, which are made fresh throughout the day. They form the basis of one of their most popular sandwiches, a simple chicken cutlet with “the works”: a blend of lettuce, tomato, mayo, oil, vinegar, and spices that make these subs at once sloppy and crunchy. Their classic Italian combo might just be one of the best cold sandwiches in the borough, especially if you add mortadella and order it spicy. It’s a great place to grab lunch for a picnic in the park or a trip out on one of Sheepshead Bay’s many charter fishing boats, which make daily trips out for bass and fluke.
