I usually love this place but tonight we went and it was a bad experience. I ordered a sub for my mom fully involved and from the receipt it looks like he manually removed all of those ingredients. All of our subs were very thin but still tasty. There is something very wrong with their beverage machine and it's been happening for at least a week. On two separate occasions my mom has complained that her diet Coke tastes sour. This evening my daughter tried to get cream soda and there was no syrup, only carbonation. I got Fanta and it was disgusting. While we were there they were restocking the chips and for some reason the lady that was showing everybody how they should be restocked seemed upset. read more

I had terrible service here. I walked in and I was the only customer in the restaurant. There were 2 employees who both saw me and neither one of them acknowledged me. I waited at the register to make my order for quite a while and almost left. Finally she took my order. I remained the only customer there yet I waited almost 15 minutes for my one sandwich (I timed it). Why should it take that long when I am the only person there?!! Im pretty angry I included a tip in my order. I will NOT be coming back to this place. I dont recommend it to anyone who hates to be ignored. read more

Well, I know I like Jersey Mike's Way better firehouse subs skimp on the meat and their subs were small and mediocre for the price. Jersey Mike's is way better. The store on Grant Street was not very clean at all and the workers seemed overworked. Pay your people more and give them better benefits. read more

Food is always amazing as always! My server Rox was spectacular and was so very kind and helpful! She made my day just by talking to her! So full of energy and humor that made the experience very enjoyable. Will be coming back just to chat with her and get the best sandwiches around! read more

Super good food, the workers were super nice. I loved the pictures of the fire stuff on the wall it was a very fun atmosphere.

Firehouse Subs Missing order On November 24th, my wife walked into Firehouse Subs to pick up an order she had placed on the Firehouse website. Our food was not there. We found out that DoorDash had picked it up and delivered it to their customer. We found this out because the customer had called us, rather than rectifying the situation. The manager at Firehouse refused to remake our food or issue a refund. He told her there was nothing he could do and that she should request a refund online. This compounded the incident with poor customer service. We immediately notified Firehouse Subs about the issue. Jessica was quick to respond. However, she also said there was nothing that she could do as the store's POS system processed our payment. We therefore would have to get the refund from the store. Jessica added that she would forward the information to the store's ownership and management. It's been months, with no communication from the store. They took our money and did not provide us with food. That is theft. And to add insult to injury, their customer service was horrendous. We had already taken the matter up with management on site at the time, and do not wish to waste any more of our time. Sixty dollars is not much to us. But to others, it may be a lot. The reason why I am writing this review is the principle of this matter. What they did is wrong. According to feedingamerica.org, 20% of Americans are living with food insecurity. I said that $60 is not significant to me. However, for the 1 in 5 that it is, I am leaving this review.

Talked to the manager, he refused to remake our food. The manager informed us that we have to apply for a refund through the website and then walked away. Items: [][] Jessica (Firehouse Subs) Nov 26, 2025, 11:20AM EST Hi there, Thanks for reaching back out! I am very sorry to hear that you have not yet been contacted by the store leadership for a resolution. I can understand you wanting a swift resolution, and this is not the experience we want for our fans. Unfortunately, I do not have a time frame for when they will contact you, but I have updated your case and it has been escalated to the restaurant management team. I have also requested that they follow up with you about this as quickly as possible. I have also alerted the store manager, letting them know that you still have not heard from the store yet. The leadership will try to contact you through your cell number, so please look out for unknown number calls that you might receive.   For the quickest resolution, I recommend you contact the store directly as they have the tools to resolve these issues. Once again, I am wholeheartedly sorry for the inconvenience caused and the Firehouse Subs family hope to serve you better soon. Thanks, Jessica read more

Kainus - a manager at the Firehouse Subs location on Grant Street in Thornton - provided superb customer service! I really appreciated her attention to detail and kindness for my large order to host a lunch at a nearby doctor's office. Firehouse Subs hit the jackpot with Kainus!! Thanks Kainus for all your help!! read more

People have recommended Firehouse for awhile, so decided to pick up a sub. As others have mentioned, service isn't great, welcoming, or otherwise engaging upon getting into the store. I waited close to 5 minutes at the register (by myself) for someone to take my order (not happily either). Got the sub home and it was barely toasted/warm and soggy....and then...it was somehow sweet? I thought I was crazy until I looked at the nutrition facts and saw 36 grams of sugar (that's 3 tablespoons!) in a medium. Count me out. Thankfully I was curious and in the sad little shop to grab hot sauce from their sauce bar, which was the highlight. Won't be back and will not ever recommend. There are so many better sandwich shops in the Denver metro. read more

The food is frkn delicious. I'm Huge sandwich gal and this is my favorite sandwich place ever! Service is always great and quick. Ambiance is 10/10 read more

Food was ok but not how I ordered it. The staff was operating at 1/32 speed, it took about 20 minutes to get two sandwiches. I won't go back for a while until they have time to rotate out the staff. read more

I really appreciate Firehouse subs commitment to raising funds for first responders. The service and the food was really, really good. The bread was fresh and soft, the meat was high quality, and I was impressed with the barbeque sauce on my brisket and cheddar sandwich. It was sweet and flavorful. I wished it had some veggies on it, but it was really delicious. However, the pricing is crazy high. An 8 inch sub with chips and a drink for $10 plus tax is crazy to me. Other shops I can split a foot long with my husband for less than that. They are absolutely better than the other shops, but the prices give me pause for sure. read more

0 stars. The service here is incredibly rude. Went here for my yearly birthday sub and I cannot believe the service. I was ignored most of the time and You can just tell it was a toxic environment and things were tense with employees. The nice person on the register even looked stressed and even scared of the manger. You can tell the manager is clearly rude. I hear horrible things about this location I will for sure never visit here again and highly recommend skipping this one. read more

Placed an order through the app with a stated pickup time of 4:45pm. Arrived at the restaurant at 4:50 figuring a 5 minute cushion would be plenty, and it was not ready. The employee said "give us 7 minutes." I told her that it was already supposed to be ready 5 minutes ago, to which she replied "I just walked in the door and put my apron on." What kind of response is that?? No apology at all. And there were 3 other employees who apparently couldn't complete one order? It was not busy, and the employees seemed to have time to gossip instead of work. My order was not ready until 4:58, thirteen minutes after it was supposed to be. This delay made us late for an event. I would have just cancelled the order but quite frankly didn't think the employees had the wherewithal to do that. When my order was ready, there was STILL NO APOLOGY AND NO ACCOUNTABILITY. And the sandwiches were clearly thrown together sloppily and not cut evenly. The staff at this location are very rude and, based on previous reviews here, this seems to be a consistent issue that management does not care to rectify. This location knowingly allows it's staff to be rude and lack basic customer service. And to the owner, I have already provided this information to firehousesubs.com/support read more

Just returned from this store where I picked up the sandwich that was left out of the bag on an Uber delivery. The order was for two sandwiches. They forgot to put HALF of the order in the bag. And had the nerve to hang up on me and be full of sass and zero reasonable solution. Never apologized. So, I arrived at the store and there are no other patrons. There were three people behind the counter watching a cartoon. Meanwhile the floor hasn't been swept in a WHILE and the trash is full and there are at least four tables that needed cleaning. Pathetic. read more

Just got home and opened our sandwiches. Worst sandwiches we have. Ever gotten from this store. Mine was on the wrong bread and was drowning in mustard and mayonnaise and had enough onion for 6 sandwiches. My husband had to hunt for mustard or mayonnaise on his, no lettuce, no tomato. Sloppy, sloppy work. read more

I was in a pinch after Subway tried to steal marching band money! The manager was awesome at helping us figure-out what we needed! The kiddos loved the sandwiches and I felt so good feeding the fresh sandwiches! Great job!!! read more

I just want to give a shout out to DJ. My husband placed an order through DoorDash and asked if they could switch out the turkey for Chicken, as they don't give this option through DoorDash. He was really nice and said it would be no problem. We've had issues with this prior from another lady who works here. She's always rude about it when we've asked, and even went as far as saying that we can make those changes (even though we've tried numerous times to do so). We really appreciate DJ for providing great customer service. We were close to not ordering here anymore because of the other gal, but we're glad to know that someone else answered and was really nice. read more

Decided to try a new sandwich place. Was very impressed. Bread is amazing! We'll be ordering again soon!

My boyfriend went there today at 6 PM and he's there at 6:41 PM still waiting for sandwiches to be made to simple sandwiches these restaurants are getting ridiculous read more

Every time I have gone into this store, one of the Hispanic girls has been so incredibly rude. After my experience today I refuse to go back. They absolutely need to speak with her or just straight up fire her. It's ridiculous how someone can be so immature and act that way towards customers. read more

I went there and the customer service was poor for being staffed with so many people. In addition this location does not offer a military discount even though I found several nearby locations that would. I can understand their point..... military only have to fight trained combatants.... i.e. killers. Why first responders are killing innocent unarmed people and giving us movements like "black lives matter" and LA Riots. I shopped here once and will not be back. This location seems disingenuous and left a bad taste in my mouth. read more

Great sandwich very satisfying with a lot of meat. And I also ordered chili which is fantastic. I wish I would've ordered two.

So disappointed. Place was depressing. Staff unfriendly, food not appealing. Mac and cheese lukewarm. Won't return.

Good food, horrible service. My daughter & I ordered sandwiches, waited, then was handed a bag and walked out. Got home and realized were given the wrong order- called and spoke with the "manager" who was rude, argumentative and unhelpful. She said "YOU grabbed the wrong order!" and only offered to remake our sandwiches if I came back in. We love firehouse subs- what they stand for and the good food. It's poor service that spoils the whole experience. Every time we come to this location, the kids barely acknowledge customers because they're too busy laughing amongst themselves. This was the last straw... so sad. read more

Excellent subs, a rung above the chains I wont mentions.(Subway). Clever firehouse themes, with dalmation patterns on the table and plenty o' firefightin' puns. A whole huge array of hot sauces. But ist the higher quality of meat that grabbed me!!! Just delicious , fast, well excuted. I'l be back and seeking out other locations. read more

Firemen. Sub sandwiches. Hot Sauces. Three things I love!! Put the three together and you have one of my favorite places to eat of all time! Firehouse Subs!! After living in Jacksonville, FL (Firehouse Subs birthplace!) for over 2 years, I came to LOOOOOVE and adore these subs. From the moment I walked in and was greeted with "Welcome to Firehouse!", I knew this place is a keeper. The fire decour, paintings and even little fire hats make this shop feel like you are amongst real firefighters in their kitchen! I just had their "Italian" or #4 on wheat bread, fully involved...aka loaded with goodness, and my absolute favorite. Loaded with 3 different kinds of meat, slices of yummy cheese with a pickle on the side,the italian makes my heart melt, literally :) Their selection of cold sandwiches are delicious too ( club on a sub!) Whether I get the regular or large subs, I can usually eat every last bite and with pleasure! *Don't forget to try their signature hot sauce from Captain Sorensen's own creation! If you don't like the mix of sweet and spicy, there are over 25 other hot sauces to choose from. yay! Thank you firemen, for making my sub sandwich the most delicious it could be :) read more

Very good sized subs, very fresh and a Plethora of Hot sauces to choose from! Yessssss, I finally got to use "Plethora" on here ha-ha, I did leave this place full which is more then I can say for subway! When you walk in you get greeted by everyone be hind the counter with a shout as you walk in I even heard a "Welcome to CASA De FLAGO" so along with great food they have a active positive attitude! I snapped a picture of there hot sauce selection to show you guys and they sell everything have out for use. WARNING: the 357 hot sauce don't F*#% around measured at 328,000 scoulville units for those of you that know how to measure how hot something really is, for those of you that don't Tabasco is abt 600 scoulville units so it is 547 x hotter then Tabasco read more

Firehouse Subs - Tons of hot sauce - Sandwiches Near Me - Thornton, Colorado

I've ordered from this particular Firehouse Subs months apart and both times I was sick as a dog the next day. I really like the food but I don't think it's safe to order from here anymore. read more

Nice place, quick friendly service. Only a handful of customers in (just before 5pm), so the dirty tables and floor that needed swept had no excuse hence only four stars. My brisket & cheddar sandwich came quickly and was nice and warm. The sandwich was a lot smaller than I envisioned based on the giant photos on their menu boards. However, the bread and brisket melted in my mouth like butter and I could really taste the smoked flavor. The sandwich definitely lived up to it's hype. Overall, better than the usual sandwich shops. read more

Poor customer service and the dinning area is filthy. Trashes over-flowing and food all over the floor and tables. Will not return to this location read more

Waaay over rated. I have been delivering for this place through uber eats on a few occasions so I thought I should give it a try. Not enough meat and low quality lettuce. My sandwich came with two different meats and I couldn't tell the difference at all and there was like three sad slices on it. All sauces I tried including the number 9s were not that tasty or spicy. For the price you pay, and the name, this thing should be loaded! Too many people on the line talking to each other and not making quality sandwiches. Thought this would be comparable to a subways or Quiznos. Not even Close and would rather go to those chains. Can't wait for day we get Earl of greys! read more

I dont really go to firehouse subs. But this location has GREAT customer service!!! The store was clean & well maintained. On the down side i did find a hair in my sandwich. Called the store told them what i found & they handled it very well! I would just recommend hair nets or hair up if employe has long hair. Other than that it was a great visit! Crew was nice & friendly! read more

Just went here today and I was pleasantly surprised. It's a nice little sub shop with a good choice of different types of hot and cold subs. I got the engine something or other for myself (turkey, roast beef + the works) and the club for my sig other. They gave me some little containers to bring home samples of their signature hot sauce which was explained to me as a "sweet sauce with mild heat." Their house sauce was very good and the description was dead on. The guys behind the counter were very helpful to this Firehouse noobie and since I didn't get to try the sub right out of the oven, I'll have to go back ;) If I were to compare this to subway, I would say it's a higher end version. We got the wheat and white bread and both were delicious (and not flat tasting like subway) Oh and like the previous poster, I gotta get my hot-sauce on. There were so many choices of hot sauces that I have never even heard of before! Did you know Cheech has his own hot sauce??? For some reason that blows my mind. (I'm giving it a 4 for now and they might just get that 5th star once I go back) read more

I would eat at Firehouse Subs regularly when I lived in Florida, so I was pumped to find one in Colorado! It took me a few minutes to recall what I used to order, but then it hit me---the NY Steamer---which is their version of corned beef and pastrami. The sandwich was very tasty, even before I kicked it up a notch with some Iguana XXX! The bread is served warm and fresh and the corned beef and pastrami melts in your mouth. The only reason I would rate this location as a 3-star instead of 4 is that the restaurant wasn't very clean. I went during a down-time between lunch and dinner, so there weren't many customers at the time. Even so, many of the tables hadn't been wiped down, straw wrappers littered the fountain drink area, etc... Having said that, I still hope to return next time I'm in the Denver area! read more

Delivery. Timely. Sub sandwiches and salads, chips, a brownie. Nothing special, but if you're not in the mood to cook, it works, and the owner doesn't hunt big game animals, like Freaky f*cked up Jimmy Johns. Vegetarian options available. $ read more

Great hot sauce variety. The 357 made me tear up a bit but tasty! I had the Hawaiian pork sammy which was just great! Tender, dripping and good balance of meat to slaw. Large sandwich that really hit the spot! We so had an Italian that was not my favorite but pretty good. Good chip selection and I'm loving those new drink machines with 100+ options. The staff was super friendly which is saying a lot if you see my other reviews of staff. They greeted us at the door and walked us through the menu and ordering process and even hot sauces since we were newbies. read more

These subs are pretty gnarly. Apparently this chain has over 300 stores, which I was completely oblivious to. They certainly weren't any in the parts of Michigan where I previously resided. Anyway, the sandwiches. The sandwich I got was the cheesesteak type one and it was pretty delicious. The only cheesesteak I've had that tops it is at Dibella's in Ann Arbor MI (I haven't made it to philly yet, I know I'm a cheesesteak blasphemer). The meat was cooked delightfully and the bread was damn near perfect. It's a delicate balance between meat, veg, and cheese, and they came pretty close to perfection on that intricate balance as well. They do the very amusing "welcome to (insert restaurant name here)!" shout every time someone walks in, which having 3 brothers who work for jimmy john's, I know can be either annoying for employees or a point of pride and humor. They seemed to enjoy shouting welcome here. This place had a friendly atmosphere and the employees were all very pleasant. The prices were right in line with what I was expecting and the food was 4 stars good. For hot subs, I'm coming here. read more

This is my favorite sub place that I have ever tried, it might not be saying much because I generally hate sub places. I would come here every night if I could. I get the brisket sandwich and it is phenomenal! They use quality products and it shows, you can taste the difference. The workers are nice, the place is clean. They have a ton of sauces for you to use, ranging in heats from mild to scald-your-mouth make-you-want-to-die hot. I would recommend Firehouse Subs to anyone! I wish I had tried it sooner. read more

It has ok sandwiches. They didn't let my service dog in .. but good food they gave me while I sat outside with my dog ...

Firehouse is the house of 'Ya Gottas.' Ya gotta love the sound of the ENTIRE staff yelling "Welcome to Firehouse!" when you walk in, every time, whether it's your first visit or your fiftieth. Ya gotta get a fireman's hat - easy to get if you've got a minion with you. Be prepared to get funny looks if you don't. Ya gotta know that 'fully involved' means loaded to the max: mustard, mayo, lettuce, tomato, onion. It's okay to ask to skip some topping or double up on others! Ya gotta try The Steamer, but if that's not your thing, trust me, a turkey sub is just as good! Or, take my son's advice and try the juicy, cheesy meatball sub loaded with provolone cheese and a couple shakes of oregano. Ya gotta stop in Sunday afternoons when the TVs are all set to NFL. It's a great place to enjoy a bite and watch the game without the ear-shattering ruckus a few doors down at Buffalo Wild Wings. Ya just gotta try Firehouse!! read more
