If weather permits, this tour is awesome! The tour is very interesting, even for people who live in the city, and goes up and down the Chicago River detailing the stories behind more than 50 buildings along the river. Need to buy tickets in advance.
This is the only bar that is close to the venue. If you want to head to the wedding early to avoid traffic you can stop in here for a drink pre-ceremony. It's also dog friendly, which is ALWAYS a plus!! This is where the after party is.
