I discovered Nikki's years ago when I worked at the Post Office on Wabash. This little "place in the neighborhood" was my daily go to! I have since moved to Arizona, but one of my first "home" food stops is Nikki's for the Cheesesteak!! Oh my gosh... better than Crack!! I get mine with mushrooms and onions which are cooked in with the meat, Provolone melted on top with lettuce / tomato/ mayo. Of course, they will customize it for you any way you like!
