I'll be in Chicago for a business meeting at O'Hare airport over a weekend. Would like to go out to dinner on Friday and Saturday nights, but have no clue as to what area I should venture to. I'll be using mass transportation (not even sure what kind) and am looking for restaurant suggestions along the lines of eclectic, seafood, continental (is that term still used?), somewhat trendy but not THE most happening spot. All suggestions are welcome!! Thanks.
