Found this place after a long hike in the Flatirons today. Needed to eat and find something fast! A quick google search popped this place up on my screen. Off we went. Placed an order on line and picked up (no dining due to the RONA). I had the Chicago Dog and large fry (really large fry, will have the smaller one next time) and an unsweet tea. So very good. The bestie had the 1/4 burger and said it was delish. The tea was outstanding. Will have to bring the hubby to this one! read more

Mustard's Last Stand - Chicago Dog - Hot Dogs Near Me - Boulder, Colorado

From Chicago.... this place gives the original Mustard's a terrible name. Ordered Fries and an dry Italian beef with hot peppers (ended up being fries, with no ketchup, no napkins, an Italian beef wet with hot peppers, sweet peppers and sautéed onions) who in the hell puts sautéed onions on an Italian beef? Regardless, they give Vienna beef a bad name and is outrageously expensive!! A beef and fries (no drink) was damn near 17 dollars!! If you are in the mood for a juicy savory Italian beef.... DO NOT GO HERE!!! Hell it would be cheaper to ship an Italian beef from Chicago. read more

Mustard's Last Stand - a sandwich wrapped in tin foil - Hot Dogs Near Me - Boulder, Colorado

So I was at the original mustards in Evanston in January and the boulder outpost simply outdoes the original in every way. The fries are too good... I mean srsly. Italian beef is a strong version and to be able to get it done this well so far from Chicago is a treat for this weary traveler. read more

I grew up in Chicago, so of course I had to check out this hometown chain in my new home of Boulder. The hot dog is the real deal--they get all the details right from the bun to the celery salt to the spicy giardianiera. I also tried the Italian Beef which was juicy and savory. The bread didn't quite hold up under the gravy, but otherwise it was yummy. The freshly made fries are a treat, and I love all the Chicago memorabilia on the walls. Will be back! read more

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

Great dogs, terrific burgers and fries are the tops. When you get the particular yen for a hot dog, this is your place!

Delicious authentic Chicago hotdogs served by friendly folks in a cramped-but-welcoming environment that fits the food, and one of the best values in downtown Boulder. Many alternative and kid-friendly preparations available for the non-purist. read more

Really really good sliders. Chill place and good food. Love eating here when walking around in the area. Best cheep meal in Boulder

I cannot eat at this place enough, and usually get something at least twice a week. When it comes to being able to find a good place to get good, quick, and fairly priced burgers and dogs, there really only is this one place. Anywhere else I've gone or had delivered is always like $12 for a hamburger that is just rubbish, but not here. The prices are really good for what you get and being in Boulder near campus it's more than acceptable. Everything that they have on the menu is priced incredibly well, and the descriptions on the menu is exactly what you get. There is no fluff ingredients or 5 or 6 slices of tomatoes with half a head of lettuce to make things look big. You choose the toppings and get exactly that. I very often leave incredibly full and having only spent like $10. Everything that I have ever had, has been fantastic, Namely the "Ditka" which is massive in size, and perfectly flavored, claiming to be 1/3 lb, but It seems way more than that closer to 1/2 lb. They use high quality ingredients and it certainly shows in the food. Everything has that nice grill flavor that we all love and even the smallest hamburger is cooked to a perfect medium rare, even after its delivered and been in a car for its journey through Boulder lunch traffic, its still cooked to temperature and hot. I highly recommend stopping in here if you need a quick burger or hot dog without any of the run around menu. What you think is usually what you get. read more

On Monday May, 8'th 2022 I stopped here and purchased a $110.00 Gift Card in anticipation of the upcoming Boulder Creek Fest an Annual event in Boulder, CO Since that date, I have stopped in to Mustard's Last Stand 3 times including today 5/28/2022 placing my orders using my Pre-Paid gift card. All went well until today. When I stopped in today, I had ordered 3 Corona beers and also a jar of the Green Chicago Original Vienna Relish. The first jar that I was handed apparently had leaked and was very sticky so I asked the server to please wipe it off / rinse it to remove that sticky substance. The girl then attempted to clean the outside of the jar only to fail in accomplishing that so I then asked her for a different jar that was NOT stick and /or leaking and she DID give me a different jar of the relish that was NOT sticky OR leaking. Ok, Thank You. Then, the owner of Mustard's Last Stand came out to the patio are where I was seated and confronted me very rudely. He accused me of being a drunk after only 3 beer's that I had ordered. If only 3 beer's was enough to constitute me or anyone else to be a drunk, then I suppose I would be guilty of that. So then WHY would this or any establishment serve me 3 beer's and happily accept my money for those purchases just to call me or label me as a drunk? I asked the man who was confronting me who he was and he replied that he was the "Owner" of Mustard's Last Stand. At every point during our brief exchange in conversation I was always polite and courteous with him replying and addressing him with a Yes So or a No Sir. Curious, I asked him if he was a Nazi, enraged by that question he simply replied "No I'm a Jew" Ok, I harbor no ill against any Jewish individuals at all. But then he ordered me to leave his place of business and instructed me to "NEVER" return again. I said fine and left immediately without any further conversation. I "STILL" have a current balance of $14.15 on the gift card that I purchased at Mustard's Last Stand that I will now not be able to use or redeem for any future purchases. I suppose that I am simply getting a $14.15 learning lesson and I am simply out of the ability to get all that I paid for. I now have to suppose that this is the Jewish way of doing business. I now must honestly say that "I WOULD NOT" recommend this establishment to "ANYONE" else ever! I wouldn't even take my dog there if I had one. I am already certain that I have simply been ripped off for the $14.15 balance owed me by this establishment. If you DO go here, then it is your dice to roll here. read more

I had the chili cheese dog with onions and fries with some Jamaican jerk sauce on the side. To be blunt everything aside from the dipping sauce was bland and in seasoned. The chili was the biggest disappointment, not even remotely proper hot dog chili (clearly this item is a afterthought and should be removed) only good thing I can say was the dipping sauce made it so I could stomach the otherwise tasteless meal. read more

The fries are flavorless and boring, no salt either. The chilli doesn't even have meat (What kind of hot dog place doesn't have chilli meat?? Lame) I understand they are trying to make this vegetarian friendly but have a meat chilli option. You have the ground beef for it! You could get better hotdogs at the grocery store. Save your money. Plus the cashier (typical boulder) didn't smile at all, such lack of customer service. Go to Costco for a good hotdog. It's a fraction of the price and tastes WAY better. read more

I was finally able to pay a visit to this Mustard's Last Stand location recently, after looking for something close to the transit center that had good food and beer. I recall there being a similar restaurant with an identical name in my old neighborhood in Florida, and although there was no relation between the two, I had been anxious to try it out for quite some time. Seems like it had been forever since I'd had a Chicago style hot dog. A friend had mentioned that the fries were a must try, as I believe they're hand cut and made on the spot, so I went with a Jumbo Char Dog combo with kraut, dill pickle, and deli mustard. I also got to check out a few rounds of Avalanche Amber Style Ale from Breckenridge Brewery, a local brand. Gotta admit, this was one of those places you wish would open within walking distance to your house - it was really that good! The employees were very friendly, and although it's small and there's limited seating, I was able to stuff myself, my food, my beer, and heaps of snowboard gear all into a corner with no problems. I'll definitely be back soon. It appears there's another location within the 2000 block of University Blvd. in Denver. read more

Mustard's Last Stand - Jumbo Char Dog with Kraut, Deli Mustard, Dill Pickle, and Hand Cut Fries. Avalanche Amber Style Ale from Breckenridge Brewery. - Hot Dogs Near Me - Boulder, Colorado

Mustard's is very cute; I felt right at home with the sun-faded Vienna Beef posters on the wall. I ordered the Chicago dog with everything sans peppers and sauerkraut (I've never been offered sauerkraut on a dog before...), and it was spot on for what I normally get in Chicago. They have a visitor's map for visiting Chicagoans with pins for guests to mark their places of origin. The pins are divided between Sox and Cubs fans, and I am shocked, SHOCKED, that apparently only Cubs fans travel to Boulder. SOX FANS GET OFF YER ASSES! read more

Kids Teenie Weenie Meal BLEW my mind... i shed a tear or two by the amazing flavors. The perfect sized wiener for an afternoon snack paired with a delectable serving of fries. Service was outstanding and recommend this place to all! Looking forward to my next visit. Keep up the superb work. read more

I ordered the chili cheese dog with hot peppers. It was just okay. My dog was lukewarm and my bun soggy (but I expected that). There was so much chili it was so hard to eat, you can't even hold the dog properly. A fork and knife were required. I also ordered the fries. I was excited to try these fries from the reviews, but they were one of the worst fries I've ever had. Could it possibly be that I had old fries that have been sitting out for hours? Maybe. We came in about an hour prior to closing, but that is no reason to serve someone sub-par fries. Place is a little dirty. All the tables I wanted to sit at all had seeds on them. There was NO ONE in there so there is no excuse not to have clean tables. I probably will not return if I were to visit Boulder again. read more

Mustard's Last Stand - Chili cheese dog versus teeny dog. - Hot Dogs Near Me - Boulder, Colorado

The one time I ate here the food was above average, but barely. The clever name put it on my radar and it took me about a year to get around to trying them. Given the name and that they specialize in Hot Dogs I expected more. Long story short-decent hot dogs and such but it didn't live up to the hype. read more

My boyfriend had a super sudden craving for hot dogs and I'm so glad he did. I got the Chicago style veggie dog on a gluten free bun and I was so impressed with every bit of it - delicious vegan dog, soft flavorful GF bun, and super fresh vegetables and pickles. Next time sauerkraut will be a must. Boyfriend got the regular Chicago style dog and LOVED it. Fries were cooked perfectly. I love that this place has been in Boulder for so long. And it felt so good to sit in the sun and eat delicious hot dogs - it was like a carefree summer day in February! read more

It's always delicious year after year . My daughter and I have been eating there since she was little . Now she's a C U student we sneak over to get hotdogs when we can. read more

I absolutely love this place! I moved to Colorado over a year ago and just finally was introduced to this (somewhat hidden) gem! I woke up one day craving a hot dog and my boyfriend suggested we go to Mustard's. The moment I bit into the Chicago style dog with all the fixins I was hooked! (Full disclosure: I think I ate the whole thing in under 2 minutes.) I have never been to Chicago so I can't compare it to that but Mustard's served me the best hot dog I have ever eaten. read more

Since being a student at CU, this is the only restaurant that I always go in when I walk or drive by, regardless of whether I'm hungry or not. Was not a huge fan of hotdogs before I started to eat here. Highly recommend it if you have not been it won't disappoint! read more

We came with a group of 18. We filled the shop and had a fantastic lunch. They were fast to get all our orders out. It was a perfect spot for us to grab lunch before heading out for an afternoon of sledding. read more

this place sucks!!! $13.50 for a chili cheese dog.....two bite's and in the garbage....save your money and go elsewhere

This is a Boulder institution and is a must eat for lunch or dinner if you are visiting Downtown Boulder. The Charbroiled Chicken Sandwich with mayo, cheddar, grilled onions and green peppers is fantastic. The Bratwurst with spicy brown mustard mayo, swiss and krout is sublime. The Italian Beef is extrodanaire! If you are a big eater I recommend the Extra Large! Everything on the menu is delicious and I have tried them all. 1/4 pound Jumbo Chardog me ASAP!!! read more

A great Chicago dog! Haven't tried anything else yet, but I don't think I need anything else here! read more

Love the hotdogs here and the staff are very friendly, the vibe is very cozy and comfortable, and close to the creek and a grocery store, witch is helpful! read more

Great local place! Amazing hot dogs! It's a shame their rating is effected by one racist man commenting. If you don't have anything nice to say don't say it at all Edward! read more

Enjoyed the visit. Not often do I have a chance to eat at a hotdog stand. Had a polish sausage with all the fixings great stuff. beside the food, the atmosphere was outstanding a service top-notch. Highly recommend. read more

Fine but overpriced hotdogs. The kids who work here do great and aren't responsible for the prices. Also if a place is busy, your food will take time. So give them a f***ing break. Ownership needs to justify these prices (I know rent's high in Boulder but you've been there what? 20+ years... hopefully your paying the aforementioned workers really well). Ultimately if you're dying for a Chicago dog while in Boulder this might be your best bet, otherwise I'd skip it. read more

I stop in for a veggie dog and some fresh cut fries any time I'm in the neighborhood, and have been doing so for years! Love the casual vibe and good food. read more

Second time in a row my online order took upwards of 30 minutes to arrive. I won't be back.

Best hotdogs in town! They have great service and have been in Boulder for a very long time. They give me a smile on my face after every visit! read more

I've been going here since I was in elementary school and I've never had a bad experience. The food hits the spot and the service is gruff, but efficient. In a town where every new restaurant has added some variation of gourmet seasoned fries to their menu (Garlic Fries at the Kitchen, Truffle and Parmesan Fries at Larkburger, Rosemary Fries at Smashburger...), Mustard's still gets my vote for best fries: skins on, crispy and golden, perfectly salted, unpretentious. Critics who have decided to drag down Mustard's rating because they believe that including vegan and vegetarian options prevent it from being called a Chicago-style hot dog stand need to wisen up. Boulder's Boulder. You should be thankful that this establishment has been able to survive the onslaught of truffle oil and rosemary sea salt. Final thought: this is the perfect food for grabbing and sitting by the Boulder Creek with friends. 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 took my money back and ran out the door. The owner was abusive to his employees - in front of me and other customers. I have been eating at Mustard's for 30 years. There are too many other great restaurants in Boulder to patronize this creep. 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

When driving past CU, I saw this place. It had a Vienna Beef sign and no ketchup on the dogs depicted. I demanded to patronize it before flying back to Chicago--even though we already ate dinner. I'm impressed. This is an authentic Chicago dog--IF you get it WITHOUT sauerkraut and WITH celery salt (as the man behind the counter told me he would make it for himself). They have the recipe down pat: Vienna Beef, mustard, sport peppers, tomato, etc. They apparently even have Old Style beer! If it weren't for the sauerkraut and hippie vegetarian options, no one would raise an eyebrow to see Mustard's on Ashland and Milwaukee. Prices are steeper than what I pay in Chicago, but I suppose this is the cost of exile. On the other hand, the ingredients tasted fresh and zippy. Would definitely eat here regularly if I lived in Boulder. Having been to Mustard's Last Stand in Evanstan, I would say that this restaurant exceeds its apparent Chicagoland namesake but for the price. read more

I think this place has been around for at least 30 years, and has been serving high quality food for all this time. The vegetarian burgers in my humble opinion are the best one can get in Boulder. I don't care how fancy the place is, or what they claim, nobody has a better veggie burger than Mustard's. And my family has enjoyed their regular burgers and hot dogs too. Hot dogs are really their specialty here, but they do everything well. Excellent fries too, as the other reviewer has said. Cooked in a healthy type of oil...I asked last time I was there. Fast friendly service...near the creek....metered lot adjacent that's free after 6pm and on Sundays. Great place to go get a meal during the Creek Festival, and the Fall Festival. read more

I love what the reviewer down the page said: "Makes you feel like you might really be in Chicago. I had the Tofu Rueben...my husband had the soy Italian sausage." No self-respecting Chicago style fast food joint would have these hippy dishes on the menu. Mustard's Last Stand: You lost ALL credibility. I've been here one time (back in 2008) and would not go back. Their Italian beef was awful--tough meat (and hardly any, I might add) and soggy, soft peppers. No seasoning/spice to the meat. Been reading from other reviews that they put sauerkraut on the hot dogs--that's NOT Chicago style--that's New York. They can't even get a simple hot dog right! Probably put ketchup on it, too, I'm guessing. Boulderites that have never had the real thing probably think it's good (and by the reviews, I can see they do). If you're going to try true Chicago style food, try it how it's supposed to be: Not your fake soy/tofu crap. Stay in Boulder, leave true Chicago style food alone. 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

I discovered the secret of this Mustard's! If you order a char dog, you get a Polish... and if you order a Polish, you get a char dog! For the longest time I was ordering Polishes and when I opened my order up to find a char dog staring back at me, being confused and a bit mad and, at the end, still craving a Polish. Dan was like, 'well, why don't you order the char dog then and see if it's actually a Polish?' and I was like, 'that's a totally ridiculous idea...' BUT HE WAS RIGHT and now I am able to eat Polishes! And they're not bad! They still don't measure up to the ones in Chicago, but really, who expects them to? They're close enough to semi-fulfill a craving. Too bad you have to crack a code first. read more
