I am coming to Chicago this week-end to visit my son and family and they want me to choose between these two restaurants. We've all been to Chalkboard and enjoyed it, but my daughter-in-law is feeling a little frisky and in the mood for something new. Is it worth taking a chance on LM? I looked at the menus (appears the winter menus are still up on the website).........we're looking for great food; atmosphere is always a distant second. Thanks....I know this is last minute.
