Famous Rv's Home of the Hoagy. This unassuming take out or sit in restaurant touts some of the Chicago-land's best French fries and mild sauce, along with its famous "Meal on a bun." This steak hoagy is chopped steak, onions, and green peppers drenched in a sweet and tangy mild sauce with your choice of sweet, hot, or both peppers and cheese. It is the type of sandwich that brings back childhood memories of long hot summer days and endless nights.
