I personally believe this to be the best bar in Pittsburgh. This place is so obscurely decorated that you're likely to miss if you're looking for it and 100% likely to miss it if you're not. If you see Ted's Excellent Bike Repair, look directly next to it. You'll see it.
This is a speak-easy themed bar and it's incredible on the inside. The windows are boarded up and the door is covered in newspaper so that one cannot look inside or out.
The drinks at this bar are on a whole other level. They are expertly crafted by the ridiculously knowledges bartenders who put long minutes into making the cocktails which range from $9-$12 dollars in my experience. While you will wait for your drinks, please realize that you aren't sitting around for a Shirley temple. These are cocktails that are made from ingredients that are located near the Seven Wonders of the World. It will come in time and it will be incredible. Sit back and enjoy the atmosphere.
Also, bear in mind that if the cocktail menu isn't for you, they have one of the largest collections of Bourbon, whisk(e)y, and scotch in Pittsburgh. In addition to this, the staff can probably tell you every minute detail of what goes into making each and every bottle of whiskey behind the bar. It's truly admirable.
This is my favorite bar in Pittsburgh. Couldn't recommend it more highly.
