I can't believe I haven't left a review for hideaway yet! This is our local bar - you know, like Mac'Laren's in HIMYM or Cheers (from the show Cheers if you've ever heard of it ;).
We first went there when all there was was a folding sign outside by the ice cream place. We walked the tiny little alley to the back and were worried we were trespassing in someone's backyard! As we retraced our steps, the Bartender happened to be walking back and showed us the way.
Nowadays there's plenty of signage and lights leading to the back. We love hideaway because it's a dive bar that's been done up nice and is clean and Jen the bartender is a sweetheart. It totally has its regulars (outside of us) that give it even more of a local Pittsburgh vibe. Though we dominate the dart board when we're there, they also have pub trivia TV thingy and non-paying slots (just for fun). They've also started having karaoke and a live DJ on some nights.
Hideaway is the perfect place to get away from the pretentiousness of shadyside and just hang out.
