I've been to Chicago once in my life but a new job will be taking me there regularly. I'm looking forward to getting to know my way around the city's dining rooms (and counters) and for my first trip out next week would appreciate suggestions for downtown or downtown-accessible (taxis? subways? buses? I know so little about Chicago at this point). Is there dining at the bar at-- is it Brasserie Jo? at any of the Bayless restaurants? I'll be staying at the Drake and am sure I'll have to resort to room service more than once so would also be interested in anything anyone knows about their kitchen.
