Having grown up in Chicago, I often find myself craving a good Chicago dog. While Mustard's delivers this for the most part, the one thing they miss on is price...and the fact that "everything" on the dog includes saurkraut, which I despise. $7 for two hotdogs? That doesn't even include fries or chips. Even if you do get the dogs fully loaded, it's just not worth it. If you're a Chicagoan in Boulder craving a good dog, my advice is to head to the Pearl St. Mall and find one of the hotdog carts. Eddie's cart by the courthouse has 2 hotdogs with everything, a bag of chips and a drink for the same $7, and that includes a tip! read more

This was the worst chili cheese dog I've had in my life. For 6.29 mind you! You get a better dog from the gas station. Chili was all beans, no meat. Seriously. Hot dog was normal size, for 6.29! With terrible vegetarian chili. Small fry and half of them were the crunchy garbage from the bottom. Could be the worst 10+ dollars I've ever spent. Buddy from Chicago said the Chicago dogs were meh but not worth the price. That chili is terrible! read more

I love this place. Great spot to get in, eat your food, and leave. It's just what you need when you need something quick but not necessarily fast food. I would recommend to anyone visiting boulder as it seems to be a great local place! read more

I took my boyfriend and his friend, who was in town for the weekend, to Boulder to show them around. Since a lot of restaurants have changed since I've lived there, we were looking for a hamburger stand to quickly grab a hamburger and head to Denver. This was the only hamburger stand that shows up on Yelp so we decided to give it a try. Our friend got a hamburger and hotdog and said their hot dog was great but the hamburger was another story. I only ordered the hamburger so I could only speak for that, but the buns were stale, the meat was dry, the service was crap, and overall I didn't think the hamburgers were that special. read more

Paid parking sucks. The restaurant is cool and small inside. It was crush time at lunch the other day with the line almost out the door and almost all seating taken. Placed my order for a Chicago Dog ($3.25), a small fry ($1.60), and a large drink ($1.90). With taxes it came to $7.31. Not a cheap lunch. The dog did not snap when I bit into it which is what I used to have happen when ordering dogs in Chicago. Perhaps due to the lunch rush the dogs were not cooking as long as is necessary. Also, I have never seen a Chicago dog with kraut before. I had to have them minus this off because I don't think this is how they serve them in Chicago. Fries were okay if not greasy. I've had better homemade fries. And yes, I ate in, so the fries were hot when I ate them. The bun was almost oversteamed - it almost fell apart on me. There really needs to be a bigger dining room here. Yeah I know on the nice days you can go to the park but when it is hovering around 30 no one was sitting in the park. If you add in the parking ($1.25 for an hour @ the city lot next door) its almost $8.56 which is pricy for one small dog, a small fry and a large drink. This place will suffice if I am close by and get the craving. It wasn't horrible but it wasn't 100% authentic. It takes more than Vienna posters for that. Guess I will be heading back downtown to Denver to see what's down that way. Overall it was a solid 3. If they worked on making the dogs have a bit more bite to them, cleaned up the fries a bit, and watched how the buns were steamed then I'd give them a 4. read more

The place is WAAAAAY over priced. (You pay less in NYC, on the streets and their hotdogs are DELICIOUS!) The hotdogs are small, average and absolutely NOTHING special; that includes the buns. The minimum amount of fries you get were burnt on the edges and soggy. Lastly, the place is FILTHY. I think the only reason it's busy, during the week, is because of its location, at the University, with the many wealthy students that have money to burn at this awful place and are just desperate to eat something quick. DON'T. GO. read more

Very expensive for what you get. I wouldn't go back. Best hot dog in town can be had at Costco for the price of $1.50 with a soda. No membership needed. read more

Worst corn dog I've ever had. It took 20 minutes for me to get it, and it still wasn't cooked through. What happened to this place? I used to think it was so awesome. Oh, yeah. I used to be a vegetarian. read more

The name always intrigued me but there are so many good restaurants in Boulder and when visiting so little time. I wish I would have tried this hot dog gem sooner. Yes, you have to pay for parking get over it! The next best thing is in Chicago and the last I checked SouthWest is getting $290 for the Wanna get away flight. That's an expensive dog! The Vienna hotdogs were fantastic and the hand cut homemade fries were even better! I will definitely return to this Boulder institution and try the burger next time. I highly recommend trying this spot. My wife said to mention they have tofu dogs and burgers as well. read more

Straight up yum. Molto yum. Also great a/c on hot days. We always get the basic dog with homemade (real) fries and leave with full bellies. Go before or after noon - it gets busy. read more

Best dogs in Boulder or anywhere on the front range! Super burgers and fries too!! Great service, friendly staff, delicious food. The owner is still the original founder from the 70's. With all the new age places opening up in Boulder, it's nice to have an OG authentic place like Mustard's still around. Hope it stays here for decades to come!!! read more

This place has stood the test of time. Real hot-dogs, real good. No boulder attitude at all. read more

I have to say, this joint has really good hot dogs...BUT, there is still some improvements they can make. My father ordered the Italian beef and sausage combo, and the sausage came out almost burnt on the outside and was dry. It was delicious and hot, but the sausage was just burnt. My Chicago dog was alright. The bun was nice and hot, but it was missing celery salt, and also they suggested adding sauerkraut to the chicago dog. Who does that? Sauerkraut isn't even part of the Chicago Dog! Who came up with that idea!?! Anyways it was okay and I would come back here again. Just don't give me the sauerkraut in my hot dog! read more

I am such a fan of Mustard's that my coworkers know a good gift is a certificate to this location. To be fair, I work around the corner so I am awfully biased. But I also know that I have had so many bad veggie burgers in my lifetime --- and thankfully, the good people at Mustard's have ended this streak. Everything I have had off their veggie-friendly menu has been spectacular, but the tempeh burger is truly unparalleled. I endorse their tofu reuben and soy hot dogs with all of my being. Add to that their handcut fries and I am one happy camper. Adorably, they also offer blankets for those who may be interested in having a picnic by the Boulder Creek. Geez, could this place be any better? Unfortunately, since the place is so awesome, you have to pick when to go. This location is popular with the Boulder High students during their lunch periods, which makes it nearly impossible at times. Seating is limited, but there's reasonable turn over during the calmer periods. Take advantage of a spot outside whenever you can because the people watching at Broadway and Arapahoe is pretty priceless. read more

This place has always been a good spot - but they went over the top with their Family Pack Curbside. They had the coolest pack of hotdogs, lovely fresh buns and all the "fixins" - it makes 10 complete dogs and was just awesome! Every family celebrating a graduation or having a family gathering during this trying time should purchase one! Lifts your spirits and satisfies the tummy! Thanks for putting together a great experience! read more

The place is usually dirty and hard to get to unless you are already downtown on foot but there is something comforting about a decent old style dog on a steamed bun on a summer evening. Take the dogs out and eat somewhere nicer. read more

I've never been to Chicago so I don't particularly care about "authenticity" when it comes to hot dogs. Anything that I crave on a regular basis must be amazing, so what else matters? I always get the same thing- hot dog with everything, small fries, cheese sauce- so I can't say anything about the rest of the menu except that everyone I know has a different favorite so it must all be pretty good! Last night we picked up some take-out, and realized upon getting it home that they'd left out the chili dog. My dad called and they already knew and apologized profusely. A hot chili dog was delivered within ten minutes, along with a giant cookie. Now that's service! read more

absolutely delicious. was craving a dog and had one in hand within 15 minutes of leaving my house. meat is 10/10, mustard & ketchup are also superior. absolutely adorable atmosphere and i will absolutely be back. service was also incredible (went w my vegetarian friend and asked her questions about her diet. amazing!) read more

I don't care that it makes me a bad person if I like hot dogs... They're delicious. And, no, I don't want you you to tell me what's in them. Mustard's is pretty tasty. I'm not a huge fan of all-beef dogs, but whatever. The poppy seed buns seem to make them somehow taste better. I like an MK dog so I can't speak for the Chicago-style, but my friends have had good things to say about them. I am in love with the fries and could make a meal out of them by themselves. Their little shop is cute but kind of cramped. Your best bet is to wait for good weather and eat outside at their picnic tables or take your order to go for a picnic elsewhere. Overall, when I'm craving a hot dog and don't feel like driving to Denver, Mustard's hits the spot. read more

As a hot dog addict I'm constantly craving a fix. Mustard's Last Stand; conveniently located between campus and Pearl street is the perfect restaurant for a quick, fresh, hot dog with friendly service and expansive menu options. I always stick with the classic hot dog and I've never been disappointed. Definitely becoming a regular at this joint!! read more

Lived in Chicago for 50 plus years & ate hundreds if not thousands of hot dogs. Mustard's last stand nails thier Chicago dog,.

Thank God for this little piece of heaven in Boulder. Mind you, if you're not a fan of a Chicago beef or the Vienna hot dog, using the word heaven to describe Mustard's probably sounds ridiculous. But if thoughts of an authentic shredded roast beef soaked in au jus and laced with spicy giardiniera makes you itch like a crack addict, then heaven is a spot-on comparison. I was born and raised in the city. Having lived and worked all over the world for the past 20 years finding little establishments that serve food from home always makes for a wonderful day. Mustard's is such a place. The interior is cramped and some of the staff is inexperienced when it comes to serving a proper beef but they deliver what you walk in for. True taste of Chicago. read more

Hubby and I each had a double cheeseburger with the works. The cashier was gracious enough to allow us to borrow a blanket so that we can have a picnic by the water. Our burgers were very fresh and tasted homemade comma my only complaint is that all of my cheese stuck to the wrapper :-( read more

Mustard's Last Stand - Double cheeseburger - Hot Dogs Near Me - Boulder, Colorado

My boyfriend and I went last night! We chose to eat there because of the cute name (History major here), and ended up getting much more than a cute name in the end. The menu has both meat-eating and veggie options which was nice. I got a Chicago dog. We split a large order of fries. All the food was hot and freshly prepared, not to mention delicious! The guys behind the counter were friendly and knew what they were doing (so the food was ready fast!). I can see Mustard's Last Stand getting crowded during warm summer days, but it wasn't too crowded on a cold Friday night in April. The parking is also City of Boulder regulated (meaning you have to pay to park). So that's kind of a bummer as well. Overall, I would totally eat here again as well as suggest it to my friends! read more

Basic old hot dog stand complete with the rancid ketchup bottles and fake wood facades. The Chicago style dog was good. I thought it was interesting they put sour kraut on it though. The fries were very crunchy which I appreciated, but had to dip them in malt vinegar and BBQ because the ketchup was wierdly sour. Place feels kind of dingy and out-dated. This place isn't really cheap either. Boulder classic my ass. read more

I was in wonderful Boulder, Co for some training and went to Mustards for a quick lunch. I liked this place. I got a very good vegetarian hot dog, one of the only place I think you can get one. I got the vegy hot dog, a small fry and a root beer. Awesome and so American/patriotic. While eatting, one of the workers struck up a conversation with me who stated that the American hot dog is a dieing food and I though humm kind of yeah. Where else can you get a good hot dog a Rockies game. Other things I Iiked about this place is the inside seating you can stare outside to the people walking by and the outside seating is nice. One things that I did not like is the that fact that the only place to find parking is in the lot next to it and you have to pay. Pay for parking ahhh come on. read more

Best. Restaurant. Ever. If i ever become famous or rich and get to dine at places like Jean Georges, Eleven Madison Park, Le Cirque, Le Bernardin, or Per Se i still dont think anything will ever add up. Not just the food, but when i walk up to the counter and they know my name and order, i just love that. Maybe its the childhood memories that have blended into adulthood like so many Boulder sunsets but I still think i would like this place on my first try. Maybe one day i will get to taste Haute Cuisine in NYC. If i ever do, i will probably compare it to Mustards and lets just say i dont envy them for that. read more

I've had both the italian beef and the hot dogs. Both are equally as delicious! The fresh cut fries are some of the best I've had in Boulder. Good food, not too expensive, friendly guys behind the counter. What else do you need. To the reviewers who complain about paid parking, don't be absurd. Pretty sure that's on the city of Boulder not on the actual restaurant. read more

Good fries, and all beef dogs. Delicious selection at a low price. Also takes meal plans which is good for students. I however just like the overall vibe, and tastiness of the fries. read more

Best tempe burger! My goodness how do they do it so well for all these years. This place is a gem, run by great people. You can even park for free, just put your plate number in the kiosk. read more

Braut sandwich was good, fries were over cooked, service was garbage. Tried to pay with $12 in quarters + $12 in cash, guy says "someone is going to have to count that later, I'd prefer to not accept that money" My bad someone is going to be so inconvenienced with counting my money. Wish that was my problem. Fire that kook read more

This is my favorite place in Boulder for food. I'm from Chicago and every time I'm sad I get food from Mustards and it makes me happy. I've never had a bad experience here and I've eaten here a lot. Friendly staff and very delicious food! read more

I would give it 5 stars but the only reason why i didn't was it was lil expensive (kids menu) and our burgers were kinda burnt and dry but the hotdog delicious and would come here again! Great menu options fast fresh clean friendly! read more

Mustard's Last Stand - Pretty neat I'm feom chicago and it was pretty good - Hot Dogs Near Me - Boulder, Colorado

See all

I'm really not a food snob but GOSH. 1) The cashier had in his AirPods so he couldn't hear us and put in "Wilson" when we said "Russell". 2) Shouted "Oh fuck I burned the shit out of this" in the back before a few minutes later calling our incorrect name. 3) Got BOTH of our hamburger orders wrong (to an embarrassing degree) and was disgustingly charred. We tasted the grill more than the meat. Don't try this if you're wanting a nice quick eat. Just an overpriced place hanging on by it's Chicago "looks". read more

After living in Boulder for almost a year we finally visited. We'll definitely be back!

I'm new here and still discovering what great food places resides here in this lovely town. I stumble across this lovely greasy spoon or should I say delicious spoon. The bison burger here is to die for. read more

I fly back from LA just to come home to this hot dog! The Jumbo char dog tastes better than any hotdog in Chicago and my mom used to live in Chicago and she agrees with me! This is going to sound like a great joke to Freud but I dream of these hotdogs they are so amazing!!!! read more

This place has been in Boulder forever. I remember it back in the days I went to CU but I never tried it until recently. The food is fine but its over priced. I've tried the cheeseburger which was tasty but small and messy and the corndog which also tasted good but was triple the price of other places. Maybe there is something I'm missing but I don't get its popularity. read more

Pretty cool Chicago hot dog place. I really enjoy the Chicago dog had nice Spicer with a sports pepper they had a nice neon bright green relish and onions. I also came back another time and order the meat sandwich and it was okay I rather got the hot dog next time. A little pricey for a hot dog but the flavor and the quality of ingredients was on tip. read more
