River North was once an area of factories and warehouses, but today this district has an arty feel. Don't miss the Eastern Corridor that stretches from the river to Oak Street to the north and from Clark Street to Michigan Avenue from east to west, and the art galleries concentrated around Wells Street, Orleans Street, Superior Street and Huron Street. You should also take in the Mart District and its colossal emblem, Merchandise Mart, as well as enjoy an evening stroll to experience the buzz along Hubbard Street, Ohio Street and Ontario Street.
