Everything about my experience at Butterjoint was fantastic. I came at 7 on a Thursday evening and the bar was completely filled with a true mix of people, mid 20's to mid 70's. After waiting a bit a friend and I were able to secure a seat at the bar. I think this may be my preferred place to sit because watching the bartenders mix up all of the creative cocktails is pretty entertaining.
My friend and I both had the burger which is made completely in house from high quality, local beef; they break down whole sides of beef to make their own master burger blend. I can say with complete conviction that the burger coming out of that kitchen is the best burger I've had anywhere in Pittsburgh. It was cooked edge to edge to a perfect medium rare (that's what the kitchen recommends), perfectly seasoned, and served on a white bun that holds up to the juiciness without being super bready. Pair that with some shoestring fries cooked in tallow (rendered beef fat), a great beer, and you have a burger and fries meal that can't be beat.
I'm sure everything else on their limited menu is just as good as the burger and I can't wait to come back and try it all.
