Hi...I'll be traveling for work to attend a conference in Chicago and we have work related dinners on two of the nights. One of my colleagues is deaf in one ear so loud restaurants are difficult for him. Hoping someone could suggest 1) a great upscale restaurant that is on the quiet side (would David Burke's qualify??) and 2) a more casual restaurant that appeals to most palettes...the group going out this night has limited funds to spend and there are some picky eaters in this group. Thanks so much!!
