You could say unmixed drinks are the specialty at this bar on the ground floor of the Chicago Board of Trade Building. Order a rum and Diet Coke and you'll get just that: a glass of rum with a can of Diet Coke on the side.

This is a Monday through Friday happy hour hotspot that's popular with traders and with locals who work in the Loop. But its West Jackson Boulevard location also makes it perfect for travelers looking for affordable drinks (and snacks) between the Art Institute of Chicago and Willis Tower, two of the city's top attractions.

Just get there before 8 p.m. This is one Chicago bar that pours its $5 drinks stiff and closes its doors early.
