We really love Catalyst Hot Dogs! A guy from Jersey makes the best Chicago Dogs in this area! Their food trucks don't often make it deep into Howard County, so we watch their weekly schedule on social media. This time, (Apr 2026), the "big" one of their two food trucks was among the dozen vendors invited to Food Truck Friday at the Elkridge Volunteer Fire Department. This larger Catalyst truck serves their full menu: dogs, smash burgers, chicken sandwiches, fries, soft drinks, and more snacks, sides, and sweets. Their menu has ten dressed dogs, vegan dogs, and fourteen toppings for build-it-yourself requests. There are combos that save you a few dollars. Ok, usually, they have those soft beverages, but for this event, the VFD is the sole beverage-seller, at good prices, as a bit of a fundraiser. Of course, we get Catalyst's Chicago dog! Tyler always has poppyseed buns he makes from fresh-baked rolls! They make a perfect mix of toppings with genuine short bitey sport peppers, bright tangy relish and a pickle wedge, fresh dense juicy tomato chunks, bright chopped white onions, good old yellow mustard. Every bite is a delight. Find a Catalyst Hot Dog truck. Get one of the best dogs in the area! For those who wont get to Chi-town any time soon, dive into this Chicago dog. It's authentic! And while that's our go-to, we admit we're coming back to try other vendors at Food Truck Fridays at the Elkridge Volunteer Fire Department! But most of all, we're looking forward to Catalyst Hot Dog's brick-and-mortar opening in Burtonsville in the fall of 2026! Oh, and a pro tip: If the listed hot-dog event is at a smaller venue, call that venue ahead of time. Sometimes the events cancel or change dates without enough notice for Catalyst to post about it. Please don't ask how i learned this ¯\_(ツ)_/¯ read more

They have plenty of options on the menu from a variety of hot dogs to nuggets, burgers, fries etc. Congratulations on the upcoming store front in Burtonsville. Whooooo-hoooooooo!!!

I've been stalking this Jersey guy for a long time, finally got a location code enough to me to visit. Saint Mary's St. Nick Night, Dec 6th. How did it go? WELL WORTH THE WAIT! We met Chris and he told us he was making our dogs "special"! I had the Chicago Dog and my friend had the Chili Dogs with cheese combos! We had a great time and we will hunt him down...err...I mean, look for him again! If you haven't tried them, you really SHOULD! And hey, A Hot Dog IS a Sandwich! read more

Finally had a chance to have a Chicago dog from the Catalyst food truck. I have been searching for a the elusive Chicago dog every where and Catalyst is one of the only places you can find one. Since there are two food trucks that circulate the DMV area, it is a bit hard for me to find them in my spare time especially nearby. The hot dog was tasty and definitely worth the wait, there was a short line that moved fast. The service was excellent and with plenty of smiles. I ordered both the Chicago dog and the Texas chili dog with cheese. Wish I had known for only a couple of dollars more, It could have included a drink and chips. I would love to try some other toppings and appetizers the next go around. read more

Our group stopped at Catalyst Hot Dogs during a 7 day hot dog road trip. It was National Hot Dog Day and they were set up on Prosperity Dr. next to the Lexus dealership. I think they had initially said in the Home Depot parking lot so if you can't find them just do a quick loop of the area. We parked in an empty corner of the Lexus Dealership and didn't have any problems. The Instagram post said they'd be set-up starting at 11. Our friend who got there at 11:15 told us not to rush as they weren't ready yet. When we arrived at 11:25, they were just taking their first customer. The big trailer was at our location so we got to try a variety of their dogs. Really wanted to sample their garlic knot hot dogs but they were out. Our group ended up with: A Nico Suave - delicious, really liked all the condiments and those potato stix giving lots of crunch 2 Lincoln Logs - just ok. Feels like a riff on a Seattle dog but the plain cream cheese and nothing else left us wanting more flavor. Seattle dogs have grilled onions. I think a scallion cream cheese or even everything bagel seasoning on top of the plain cream cheese could make this delicious. A Dog House - simple. delightful. A New York Dog - really good. Hot onion sauce had that little bit of spice and a Side of Fries - well-seasoned and hot Gentleman in the truck confirmed our order with us a few times just to make sure we got everything and we did. A $20 two specialty dog combo seemed like a touch expensive *in this economy* but everything is expensive now and I could tell these folks are using quality ingredients. Keep up the good work Catalyst Hot Dogs! read more

Got to try the truck while visiting Brookside Gardens for their Garden of Lights. The line moved slowly but it did move and the guys were working so hard to get orders out. We tried the classic dog, the Icelandic one, and a smash burger. Everything was very tasty. Their fries are good too but perhaps over salted. Love that they offer vegan options too for the hot dogs. Definitely recommend - very family friendly truck. read more

First Quality hotdog, very nice bun, Texas Chili sauces surprised me because I saw a thick sauce that did not have the texture of chili but was more like a smooth paste. That sounds Kinda gross but I just couldn't think of the right word. The flavor was very tasty. Really enjoyed the hot dog, highly recommend! read more

I like a good hot dog but it's not something I usually crave but one night while I was in the area, I decided to finally check them out. The inside is a standard bar with plenty of liquor and TVs. There's also a lot of outdoor seating, which is what I chose. The lady at the front was really friendly and even offered my dog a bowl of water. I decided on the chili cheese dog, fries, and a side salad. My daughter ordered a cheeseburger kids meal. The food was good. I loved the thin and crispy fries. My daughter loved her food. All together, my experience was good but I can't wrap my mind around paying $31+ for a hot dog dinner again. read more

Hot dog was cooked really well and loved the toppings with it. The burger was good but it said it came with lettuce, onion, and tomatoes but then had nothing on it.

In response to the owner: You mad, bruh? We were really looking forward to checking out Catalyst Hot Dogs, as both the photos and the menu looked tasty. We made the trek to Denizens, which you can grab a table or order at the bar for to-go. We ordered: +Hanks - this came topped with Texas chili sauce and cheese - I personally was looking forward to this, because I do like a good chili cheese dog, but we both were just not fans of the chili +the Chicago Dog - topped with sport peppers, green relish, tomatoes, onions, dill pickles, yellow mustard, and celery salt; this came in a poppy-seeded bun; I thought it was interesting that all the toppings were diced and mixed; I guess it was easier to eat? +the UMD-OG - topped with black bean puree, corn sauce, fried red tortilla strips, and cotija cheese; this may have been the 'more preferred' one out of the three, but the corn sauce was too sweet for us, and the tortilla strips were stale and chewy, and not crispy as we thought it would be +and, Disco Fries - fries topped with gravy and mozzarella; these were actually okay, but it seemed as if it was more cheese sauce than gravy; it would have been great if there were more gravy in there; definitely have to consume this right away, as the fries do get soggy quickly All the hot dogs looked tasty, with the split ends and a bit of a char; however, the hot dog itself was pretty bland - this was pretty surprising, as we had rave reviews of their dogs. All the buns were super dry and stale, and there seemed to be some toasting action with the dry/stale buns. We were also hoping that the items came out piping hot, as we thought we were waiting for made-to-order items, but everything was lukewarm at best. Staff were friendly, and there were some patrons dining inside. We wished we had the same tasty experience as others have had, but it was pretty disappointing; we ended up tossing most of the items after a bite. +dry/stale buns +friendly service +located inside Denizens Brewing Co. +street parking available read more

The all the ways dogs. The bun was very tasty as well as the chili. The snap of the hotdog was extremely pleasant. I never had a hotdog cooked the way this one was. The onions I wasn't a big fan of but that's a personal preference. It does have mustard as well as all good hotdogs should . The rating for me was impacted on the price. A little order $16.96 for what you see in the photo is pricey. read more

Despite having been shot by Sofia, John Wick secures her reluctant help in setting up a meeting with her former boss, Berrada, because Wick once rescued her daughter from an impossible situation. John, Sofia, and her two expertly-trained Belgian Malinois, wearing bulletproof vests, stroll into Berrada's headquarters, all-too-cognizant that, at a moment's notice, the situation could turn sour; and it does. But what if this weren't dystopian fantasy? And what if, instead of the location being Berrada's Moroccan hotel, it was at Denizens Brewing, located at 4550 Van Buren Street in Riverdale Park, Maryland? There, the dogs that Sofia could order to assuage her hunger or quell that of her would-be assassins are not Belgian Malinois but rather the all-beef variety; and the cheese, chili, and onion toppings provide plenty of ammunition, beginning at noon every Monday through Sunday. read more

Had to get here, hot dog guy that l be. Got here at the start of happy hour. Almost empty but that's cool for me. Had the wifey with me so they were aware they needed to be on the one. All of the dogs are "rippers" or deep fried so keep that in mind. Both were good my other half had the bratwurst and she loved it. Split an order of rings which were good as well. Service was Great! Will come back for sure! read more

Catalyst Hot Dogs - Capital City & All the Way - Food Trucks Near Me - Rockville, Maryland

Catalyst Hot Dogs is the culmination of a chef chasing his dream of hot dog truck ownership and a fine upbringing in the state of New Jersey that helped develop his love of hot dogs. I know that a lot of people point to Chicago as the United States mecca for hot dogs, but I have always felt that the Garden State is the true hot dog capitol of our great nation. While Chicago has created the hot dog that beats the Windy City's name, the aforementioned Chicago hot dog, while good, simply cannot compare to the hot dogs that New Jersey has brought to the table (a little pun intended there). Now I might be a little partial to Jersey, being from there,, but New Jersey has, at least in my opinion, inspired two iconic hot dogs to Chicago's one. Yes, Chicago Has the Chicago hot dog, but New Jersey created the Italian hot dog, two hot dogs with fried potatoes, peppers and onions on pizza bread and New Jersey also created the Texas weiner. A Texas weiner is what many have called a Coney Island or simply a Coney. It is a hot dog topped with spicy brown mustard, chili and raw onions. This to me is the perfect hot dog, the culmination of hot dog and toppings. Truly a culinary wonder. Catalyst Hot Dogs has this culinary wonder. It really is no wonder as the owner is originally from New Jersey. Theirs is a tasty homage to these great hot dogs from New Jersey. I would definitely recommend stopping by and grabbing g a hot dog or two (or go for three). Good hot dogs and you will have the added bonus of the good karma of helping someone chasing a dream. read more

(4.5) ~ Very Good Overall. The Hotdogs have great snap & flavor. I got The Capital Dog with Raw Onions & Mamba Sauce, which is like a sweet bbq sauce;) Note: This is a Food Truck. read more

Delicious hot dogs! Tiny truck but great staff! The hot dogs were better than I imagined and I was surprised to see some Yoo-hoo here, which I haven't had since middle school. We got the $18 for a combo of 2 specialty dogs, 1 chip, and 1 drink. Honestly wish I could have stayed around longer to try the other dogs! read more

Let me start off by saying, "Will I visit again... yes. " My husband and I chose this place because of food critic we follow on TT. We went on a beautiful Friday during happy hour. We sat outside and ordered garlicknot dogs (get these), thai chili wings, Chicago dog, and smash burger. We would come back just for the garlicknot dogs. They were that good. Chicago Dog is my favorite hotdog, and this one was okay. It was small and missing bright green relish. Now, for the rest of the food is why I gave 3 stars. One word. Salt. It was missing salt. Wings and smashed burger needed salt. I order ketchup and mustard. The waitress brought out ketchup and honey mustard. When I looked at the bill, they charged me 50 cents for honey mustard. But I didn't ask for honey mustard, nor did ithey nform me that it would be an upcharged for honey mustard. Just a small lack of communication. I will be back to get two orders of garlicknot dogs and try something else. This part of the review has nothing to do with the restaurant at all but a pateron that was there. A guest had this big, beautiful white shaggy dog. The owner of the dog kept petting the dog and pulling out the fur. I mean, fur was in mass on the ground. When the wind blowed, the fur would fly everywhere, and I had to cover my drinks and food. Sir, maybe you don't mind fur in your drinks and food, but please be considered of others. read more

Coming from Philly, these hot dogs really bring me back to some memorable flavors. The "All the Way" dog was perfect. The chili was perfect for a hot dog. The potato bun is pillow soft. The best part of the hot dog was the hot dog! Perfect snap when you bite into it and great beef taste! I was only planning to eat one but had to order another one on the spot! I also ordered some To Go dogs for the family. The dogs traveled well and my wife loved them! Other fun pluses were the Herr's sour cream and onion potato chips and the ice-cold Yoohoo Thanks Chris for bringing some great flavor into DC! Can't wait to visit again! read more

Enjoyed my first visit to Catalyst Hot Dogs in Denizen's Brewery in Riverdale Park Station. Ordered a Chicago Dog and the Small Biz Cheesesteak with onion rings. HIGHLY recommend the Small Biz Cheesesteak with bread from Manifest Bakery and ribeye from Soko Butcher. The Cheesesteak was cooked perfectly and was a good size. Onion rings were solid and the accompanying sauce was excellent with a tangy taste. Chicago Dog was as expected with great toppings. The Small Biz Cheesesteak was definitely worth $20 with onion rings and tangy sauce! read more

This is seriously a great food truck. I don't usually eat hot dogs but I had to give this food truck a try, and I'm glad I did. The owner and operator is so nice! He will chat with you and give recommendations. He and his son own the food truck together. The hot dog flavor combinations are great. I think the prices are more than fair, $. I absolutely recommend coming to this food truck and following him on Instagram for his weekly schedule. His Instagram is @catalyst_hotdogs! Can't say enough good things about this. He accepts card tap payments. He has a cooler with canned soda and bottles of water. The chips are hung on the side of the truck and the menu is posted on a sign. The turnaround was fast for ordering and receiving the meal. Also, he has a rewards card. It's a paper punch card that you get punched every visit. Give it a try! read more

Since childhood, hot dogs have been my favorite food, so when I saw that Catalyst Hot Dogs was going to be across the street from my building, I wanted to check it out. Then, we had a power outage and my decision was made! I toddled up to the little truck and was greeted by a friendly fellow New Jersey ex-pat. I decided on the special, a Chicago dog. I have heard of them but never actually ate one before, so I was excited. While he made my dog, we chatted about NJ. I enjoyed our conversation. I added chips to my dog and took my delectable purchases home to my darkened condo. Let me just say, I was in heaven! I could've eaten two of the hot dogs, it was so yummy. I loved the toppings, which were peppers, relish, mustard, and something crunchy. The roll was really good, too. I need to seek out this food truck again. They make their own chili so I'll need to try the chili dog next-and get myself two! read more

I know the humble hot dog might not be everyone's favorite, but this guy just legit served me the best hot dog I've had in a very long time! Idk that I've had a hotdog that good ever. It's not the dogs that sit in water all gross, it's seared to perfection. He has a ton of topping choices. I'm a big Chicago dog fan so i do wish he had the peppers for that. The owner is so energetic and friendly! One hot dog was huge and enough to fill me up but i ate 2 because they were delicious. read more
