I used to love the Bittersweet which was a bar, hidden up a dirt  (now paved road), attached to a ranch house complete with a swing  set in the yard.  Now its called "Skeeter's" and its tidied up a bit and the smoking ban has helped but its till a ten stool, two dart board, three table hole in the wall.  Drinks are cheap and staff is friendly.  As a matter of fact Leah is hoping to become a Loop girl, and I wish her the best of luck.
Downside? Really none, just hate when bartenders are texting behind the bar when they could be engaging me in pointless conversation and the swing set appears to be missing. Â And the smell of a sump pump or sewage in the ladies room, Yuck.
