Artist Lounge at Renaissance Chicago
With its great outdoor roof bar, Raised, overlooking the Chicago River, you might want to forgo work altogether, but when duty calls, there's ample space on the Renaissance Chicago's first floor to get stuff done. The Artist Lounge, just off the lobby, has midcentury modern-style chairs, long couches with throw pillows, communal tables, black-and-white photography and tall windows that flood the space with light while you sip Illy coffee. Another area, Bar Ritual, offers food and drink—with plenty of outlets at the bar to charge while you work. Stick around until 5:15 p.m. Monday through Thursday for some gratis boozy punch while it lasts.
