Two stars or two and a half stars? I cannot decide. Ultimately, Red Shed is as the Yelp label says, a dive bar. For a dive bar it sits somewhere between below average and average.
Everything in the bar is sticky and could easily be wiped down more often, considering it is not as crowded as many of the bars on State. The drinks are cheap and show it in the taste. Mostly everything is going to be made with rail liquor. You really are not given the option otherwise. Red Shed takes cash only and has a random ATM that is going to charge you a nominal fee for using it.
There are pool tables, dart boards, and a cash eating jukebox to occupy your time.
My experience was pretty meh overall. We visited because a coworker was celebrating a birthday and wanted a cheap long iced tea (good if that's your thing). I ended up getting a a New Castle on tap for $2. It definitely tasted like a $2 tap beer. For whatever reason the beer tasted sour and watered down. I know New Castle isn't the best, but it does not taste sour!
I also later had a white Russian while hanging out. It was $5.50, and the bartender didn't have any Kahlua (what?!) so he made it with rail coffee liquor. He made is strong as an apology but without asking. The drink was absolutely awful. I wouldn't have ordered it if I knew it was going to have half a cup of rail coffee liquor dumped in it.
I would not recommend Red Shed unless you don't have enough money to go elsewhere.
