Think big hair and leg warmers are still sexy? Sheffield's has just the event for you. From 6 p.m. to 2 a.m. on Friday, the popular Lakeview beer bar hosts "I Love '80s" night, which will feature $3 '80s shots (apparently Kamikazes, Buttery Nipples and Sex on the Beach were favorites of Molly Ringwald), screenings of classic movies like "Flashdance" and "Sixteen Candles," costume prizes for the best '80s outfit and, of course, a full selection of '80s music. On cassette, we hope.
