What a hidden gem! The place may look like any old dingy bar on the outside but SWEETJESUS the burgers are so delicious. Literally you should come just for the burgers.
I've been to ASBC twice and I got the Applewood burger both times. I love the combination of the sweet (the apples and the maple sauce) with the savory (the beef, bacon, bun, etc.) and all the ingredients are deployed beautifully.
While I think ASBC has some of the best burgers in Pittsburgh, everything else about the restaurant is ok. The fries are pretty decent but not nearly as good as the burger and their menu is a little on the pricey side. ASBC is also located in the Park Place Pub which is a small, laid-back bar with a fairly limited beer list.
But this place is actually burger heaven. If I lived in Highland Park, my bank account would be virtually non-existent because I would eat at Applewood literally all the time.
