Greetings from Chicago Mural The Greetings From Chicago Mural is located at 2226 N. Milwaukee Ave. Chicago, IL 60647. Flamingo Mural This amazing mural is part of a building.  The whole building has flamingos painted on it.  The business is called Flamingo Rum Club, at 601 N. Wells Street.   Willis Tower Sky Deck I think this is probably the second most popular Instagram spot in Chicago (after the Bean).  I definitely do not feel like the Sky Deck is overrated.  I’ve been a few times and always enjoy it.  It can take a very long time to get up to the top, so make sure you go early enough…
