I am headed to Chicago from Monday 1/22 - Thurs 1/25 for work. I am not familiar with the area and am really looking forward to finding some good dining spots near the office and the hotel. The office is on Van Buren and the hotel is the Hyatt on Wacker. I'd like to avoid the cold as much as possible so anything that is close on foot or a brief cab ride away is perfect. I'm on a per diem so moderately priced fare is best. Are there particular streets/areas near the hotel that I could check out? Particular not-to-miss restaurants that are not too expensive? Any suggestions are appreciated!
