Omggggg this is the best burger I’ve ever eaten!! I will be eating here often!!
This was literally the best burger I have had in such a long time.
Bourbon Burger, double patty. Was my type of burger. I’m reviewing this (I don’t review a lot). Because homie in the kitchen (Brandon) hooked us up after my buddy ordered a burger he wasn’t super fond on. I’ll be back. You should def come try this place. Worth it.

Backslash Burger (Formerly Fifty Fifty) offers delicious burgers in Frederick, located in the back of Olde Mother Brewery. The impossible plant burger is excellent, and the smash burgers are full of flavor, juicy, and perfectly cooked. Fries and onion rings are delicious; ask for extra crispy. Sweet potato fries are exceptionally crispy and seasoned (with cinnamon sugar), served with a side of in-house blueberry ketchup or a blueberry sauce that is so fire. The staff are courteous, incredibly friendly, and very kind. The vibe is super chill and relaxed, with ample seating and a large seating area with picnic tables. It is connected to Olde Mother Brewery for a local beer and burger, with easy access to the brewpub and an accessible parking lot. Great for families, with fast service and a best burger in the DMV rating.
