The Peninsula Hotel (on Superior at between Rush and Michigan) has an elaborate chocolate buffet set up on Fridays and Saturdays. It is $28 per person without alcohol or $38 with a chocolate martini. I haven't been to it because I happened to go into labor the night before I had reservations to go! But, I sure plan to go in the next few weeks! It looks excellent!!!
