I have a meeting at noon tomorrow (Monday)--on Michigan Ave. Taking the train. Due to that schedule I'll get into town at 9:30 & can't leave until 3:15. I had thought to go to the Art Institute but it doesn't open until 10:30. It's going to be like 9 degrees w/ windchills WAY below zero. So--need to spend as little time as possible outdoors!! Don't really want to shop all day, but can wander through stores if there are no other good options. Will be taking the bus to get around. Any ideas? Good coffee shops? something like that?
