NYC > Chicago. All the way.
Putting aside which is better, Chicago certainly has mastered the Italian Beef sandwich. Well thanks to Hank’s Juicy Beef, you no longer need a flight to Chi-town to get an authentic one here in NYC.
I’ll give it to you in their own words, because I couldn’t really do it better:
“Chicago-style Italian Beef sandwiches to New York City. Slow roasted beef, marinated in savory Italian herbs & spices, topped with a spicy (or mild) giardiniera, loaded onto freshly-baked French bread.”
