I genuinely don't know what happened here. Although it's been a while since I last paid this burger spot a visit, I now really can't claim I'll be back. They appear to still be using their 50/50 beef and bacon blend, and they were grinding/blending more meat when I arrived. The finished product itself makes me seriously question their palette. While smash style burgers aren't my favorite, I have enjoyed some good ones. The one I was served today was so smashed that any residual flavor from the meat blend was virtually eliminated. This was then overwhelmed by the sheer smack-your-face acid from the pickles and mustard. Further cementing my poor experience, the server acted as though my order was an afterthought. Probably not the attitude one should express towards any patron, much less to start the business day. There are LOTS of outstanding burger options in and surrounding Frederick. Given that, this genuinely poor experience, and the premium charge for their products; I am fairly certain I won't be back. read more

Touch screen service. Connected to a brewery which is awesome. Parking was simple. Had the double spicy smash burger with poblano cream cheese which was the start...texturally creamy without the sweetness of say a peanut butter on a burger. The ghost pepper chicken was awesome for heat. Chicken a bit basic but next time I'd just not upcharge for the chicken and stick with the amazing smash patties with the ghost pepper profile read more

We were in the area looking for food and the 1/2 beef, 1/2 BACON is what got us! It's sort've connected to a brewery, but there is plenty of seating to dine in. Everyone ordered a different burger and all were made to order. We also ordered a side of the old bay fries and sweet potato fries. The burgers were tasty and juicy. I would recommend them. The old bay fries were a bit on the salty/spicy side...had way too much seasoning on them. Overall, good burger joint. read more

Nice little hidden gem! The place was a little hard to find but I was looking for a stand alone restaurant with a big sign out front. It is attached to a brewery with a side entrance. The staff were friendly all the way around, inside the taproom and restaurant. I liked my burger but my kiddos didn't. Overall I will come back and try some of the other burgers on the menu. Also I need to check the taproom next time. I definitely recommend this place if you're a burger person. read more

Stopped by for lunch. These are some of the best burgers around. The blend of 50% beef and 50% bacon make for great flavor and crust . This is my third visit. The first 2 times I got the Oklahoma Animal. Double patty, sauteed onions and their Oklahoma sauce. This time I went a little rogue. I got their PBPB&BB 2 spiced patties, crunchy peanut butter and pickles. So weird but for some reason it worked. I paired it with a chocolate peanut butter porter from Olde Mother Brewery which is attached. Service is always fast and friendly. We usually sit on the brewery side. read more

We stopped at Fifty Fifty for lunch today. The food was fresh, delicious, and made from good quality ingredients. I ordered the Fifty Fifty lunch special for $10. This included the original Fifty Fifty burger with fries. We placed our orders through the kiosks, so no human to place an order through. But the food was made to order and we received our orders pretty quickly. The ambiance is very casual. It's colocated with Olde Mother Brewery next door. Theres lots of indoor seating and some outdoor seating. It's fairly easy to get to with street parking. I definitely would recommend coming here for a great local burger experience. read more

Cute and fun little place. Actually, it's not so little. It is attached to the Olde Mother Brewing. There is also a small outdoor section. You have to place an order at the kiosks which is not my favorite thing to do. I would prefer human interaction. We ordered old bay fries which was a little too salty. The onion rings (extra crispy) were delicious. I liked my burger with all the toppings while my friend thought his burger was a little too salty. Maybe all the toppings I had cut the saltiness. It was overall a fun adventure. read more

They are attached to olde mother brewing co. We sat at the bar and ordered from their QR code. I got a bourbon burger and my wife got a peanut butter burger. She added the sour cherry jam and said it was delicious. I got Cajun fries and she got sweet potato. Both were delicious. The service was quick. They were made in 10 minutes. It was a laid back experience for a nice lunch spot on a Saturday afternoon. read more

Quick update: 50/50 has now changed its name to "Backslash Burgers" Word through the grapevine says it's to avoid trademark infringement with other burger joints. No matter what they're called, they make a damn fine burger! read more

We went to the shooting range and got hungry so we looked up places to eat in Frederick. Came across this page and decided to give it a try. I got the Peter Piper smash burger and it was off the chain. 5 of us went and each got a different burger and everyone was highly satisfied with what they got. The place is also located inside of a brewery so that was a plus. The atmosphere was great. You can tell a lot of pipeline go there to hang out and eat. Will def be back when I'm in the area. read more

This place makes great food. Excellent burgers with unique builds, and some of the best onion rings I've ever had. I learned early on I don't need a double burger which is the default, I build a single and it's plenty for me. The staff is always genuinely friendly and the location in the back of a brewery makes it really accessible and low pressure for a dining situation. If there is an event going on in the back you can always go sit at the bar in the front or one of the many other tables. I do take out most times, I live just down the street and I order thru the Toast Local app. I typically walk out my door within two or three minutes if ordering and by the time I get there they are putting my order on the counter. Super fast and convenient. read more

Ordered online and got a cheeseburger with their herbed goat cheese on it -- very delicious, but a lil too heavy on the goat cheese. Also got their Old Bay fries which were also decent. Very reasonable prices though, would go again if craving this type of burger! read more

My wife and I went on Labor Day and Fifty-fifty definitely caught us by surprise. The place was very clean and spacious. The weather was amazing so we were able to sit outside and just enjoy the space. You order at a kiosk, which was fine with me. Otherwise the food came out very quickly. Now for the food, this place has one of the best burgers I've ever had. The burgers were extremely juicy and flavorful. Although it had sauce it wasn't drowned in it, but the patty absorbed it well. I also really enjoyed the old bay fries, could always use more, but definitely delicious. Will be coming back again to add a beer to my order. read more

Burger was really good other than it was cold. I had my phone on table and did not know they would notify by text since they took my name. Food sat on there front counter for 11 minutes without me knowing it was ready. I went to check on meal and it was sitting there in a bag with my name on it. Burger was good just cold since it say there for so long. The fries were good to other than they sat there for 11 minutes. What's sad is I gave them an $8 dollar tip in advance hoping to get good service. Instead it was the opposite. A local came in after me and they greeted him and even joked with him. We did not get a hi or anything when we came to the front counter. Just wish we had a better experience. read more

Great place. This place is split with half bar/half restaurant with seatings for a variety of group sizes. The staff are quick and always on the move. I got my food in a relatively quick time. I ordered on their ipad but they also had a counter where you can order face-to-face. I got two burgers and fries for takeout, the ogre and a make your own. Both were really good and full of flavor. The Fries were seasoned well. The prices were a little high but the size and flavor made up for it. It was messy to eat it but all in all I would recommend and would get it again read more

As we walked in, we noticed the really cool ambiance, with a laid back, street vibe. The kind of place to come with friends, but was great for our family to have lunch too. We ordered a Peter Piper, it was delicious (my favorite of everything we ordered)! The pickled cherry peppers were spicy, but not too much so it gave it the perfect kick to go with the sweetness of the bourbon molasses. My son had the Ogre burger which was HUGe, but he said was really good. We also had an Old Fashioned, which was really juicy and flavorful and a kids menu which included fries, a juice box, the burger and a burger gummy. It was so large and customizable. My daughter loved it. Regarding service, we ordered everything through the kiosk, so we didn't actually deal with people, but everything was quick, smooth. The sweet potato fries with blueberry sauce were delish and the regular fries had a lot and delicious seasoning. We fully recommend this place! read more

This place is absolutely delicious! If you're looking for the perfect burger, pick one off the menu or do a build your own. Either way it's a winner. Oh and be sure to get the french fries or the fabulous onion rings. The onion rings are my favorite. Service is always speedy and the ambience has a simple vibe with a brewhouse feel. read more

We visited for Father's Day lunch! Wait time was a little bit longer because the restaurant was Pat. We all three build our own burgers.

Burger was half bacon half ground beef unique flavor not bad. They drowned our burgers in the sauces that came on them while I'm glad it was plentiful it was a bit excessive and caused the bread to be really soggy. Everything was fresh and made to order. It's a great vibe for sure and relaxed. I definitely would go back for their events like trivia night etc. Service was nice as well. The bartender was cool and made our drinks really strong and flavorful. read more

These are the best burgers in Frederick. Nothing else needs to be said, except: Eat here!

Food on its own is 5 stars. Burger was very good. Ordering, not so much. Toast pre ordering said order would be ready 10-15 minutes. When I placed order email receipt said it would be 45 minutes. Actual wait time ended up being an hour and six minutes. Good food. Bad ordering system. read more

Tucked away inside a brewery, Fifty Fifty serves an excellent "Old Mac" burger and sweet potato fries with a unique blueberry ketchup that stayed delicious even after a 30-minute drive home. It's a total hidden gem, and I'll definitely be back to try the onion rings and their other burger options. read more

Fifty Fifty is one of the best places to get smash burgers. You can order on the toast tab app and choose to either create your own smash burger or choose one of their specialty smash burgers. I customized my smash burger with jalapeños, sautéed onions, lettuce, and cheese. If you are a spice lover like me, I highly recommend you try their ghost pepper sauce. It was incredibly spicy, but so flavorful. Fifty Fifty is a casual burger joint that has a brewery attached to it where you can enjoy beers as well. The service is pretty much self-serve, where you can order via the app or their self kiosk and wait till you're notified that your order is ready. read more

I had the PBPB&BB & Sweet Potato Fries with their blueberry ketchup. This place is amazing! The food is quite delectable.

Holy cow the location of this place is amazing. It has its own entrance or you can go back through a bar. That also serves I think pizza or something like that. The place for the burgers is amazing. The atmosphere is great and it probably is the best burger I have ever had. I got a double cheeseburger with bacon and their sour cherry jam. read more

These burgers are truly hard to beat. They are the perfect size and the fries are amazing as well. We will definitely be back!!

We entered through Olde Mother Brewing, but they were so nice and directed us to the right place! Ordering was super easy at the kiosks with LOTS of options. The lunch special is perfection, the burgers are "bussin'" according to my kiddo. Old Bay fries were great, but could be overwhelming if you're not an OB person. The sauce was SO good, easy and friendly service, cool, large seating area and very chill. It was a quiet weekday so we parked on the street at a meter. Bring quarters. This place was exactly what we wanted. read more

Reallyyyyyy not a fan of the pickles. There was a short period of time when they had dill pickles but apparently that was a fluke. Deters me from ordering a burger period because the pickles they have are not good. The other thing is that they do not accommodate plant based burgers for kids meals. My niece really wanted a plant based burger & tots but they insisted they do not do that & it was an up charge to accommodate. Many children I know are vegetarian/vegan! read more

Delicious. No notes. Easy to order, quick to make, yummy. In the same space as a brewery so easy to get a beer or play games

Lord almighty this truck knows how to make a mean burger. This is one of the best burgers I have ever had in my life definitely in the top three best burgers I've ever had. I would have never thought this combination would work out on a burger, but it blew my mind! The service is fast, it's a good truck lol. Great people run this truck, smiles, jokes, they just looked they were having a good time. Writing this review and looking at this burger, makes me want to go back to Frederick and order it again! I mean come on it's a burger with peanut butter look at it! it's a masterpiece. The quality of these burgers speak for themselves. Make sure you follow them on Instagram to figure out where the truck is going to be next. Fifty Fifty 10 out of 10! #eatfiftyfifty read more

One of the best smash burgers I've ever had! Goes great with Olde Mother's beer on tap! Got the Old Bay fries and they were delicious but a bit overly seasoned and very salty - probably go with the regular fries next time. Definitely recommend and will come here again and again! read more

I finally made it out to fifty fifty after many attempts over the past year. Coming into it, I had very high expectations of this establishment as it comes very highly recommended. The customer service is a bit non-existent, but that is okay for this type of place. When you arrive there is a self-service kiosk for you to order and it has all of the options on it that you can think of. I ordered a build your own with an order of their onion rings. One cool thing about the kiosk is that the order and status goes straight to your phone via text message. This is important because if you wonder over to the brewery side to order a drink you don't have to worry about missing your food. The food was hot and fresh (everything is made to order). I'm also a big fan of the potato roll for the bun. Their burgers and half bacon and half beef. With that. The burger to me was very underwhelming. I expected a nice crust on the smashed patties (none and just cooked to barely temp) and it lacked a lot of flavor. The onion rings were very good and seasoned well as they were piping hot. Overall, it's a good place to eat but not quite as advertised for me. There are better burgers in Frederick. The inside is very nice and open with plenty of indoor and outdoor seating. Also, if you want ketchup they give you on little container with a lid on it about half full). read more

Delicious burger. Of course because it's 50% bacon it's gonna be a little greasy. Not my #1 burger but still very good. And you can't go wrong grabbing a local brew and a burger. read more

Best burger we have had in years. Attached to a brewery. We were so happy we decided to eat there. You don't be disappointed!

The burgers here are fantastic. If you really want the amount of meat you'd get in a "traditional" burger, I'd recommend ordering double meat since the patties are smashed pretty thin. I've tried several of these burgers and you can't go wrong with any of them. They also taste especially great with a beer from the brewery it is sitting in. read more

I ordered the Ogre burger. The burger party itself wasn't what I expected. I was more expecting a thick juicy smash burger, but instead it was thin and wasn't really juicy. The description said there was tiger sauce but I didn't see or taste any. The bottom bun was also very soggy. Overall, I wasn't that impressed with the burger. We also ordered the old bay fries and there was way too much old bay on them and they were very salty. The service was decent. The men making the burgers were fast and helpful. I like how Toast system texts you and lets you know when your food is ready. I liked how it was intertwined with the brewery. Burgers and beer for the win! You do have to order them separately though, but that's ok! Plenty of seating and there's outdoor tables and chairs too. read more
