We are visiting Chicago from NY for the first time and will stay for 4 nights. Kids, ages 10, 8 and 3 are as foody as kids can be at that age and well behaved/accustomed to restaurants. Can someone suggest some places in the Loop or within a short cab ride or walk? In particular, what is best bet to try traditional deep dish pizza? Ribs? Steakhouse? Fun atmosphere for kids? Thanks!
