Came here for a late lunch on a Monday and it was pretty disappointing. We had the fried pickles, the Cuban sandwich and the orchard chicken wrap. Our server didn't seem too happy that we showed up today, the food took about 30 minutes to get to us and the fried pickles and the Cuban weren't very yummy, we didn't finish either. Disappointing. However the French fries WERE very yummy! And the wrap was unique and pretty good. It's a large space and it was easy to find a seat. The artwork is beautiful. Luckily we found street parking so that was easy too. It's a cash only restaurant (or local personal checks) and while it wasn't a problem, we had cash, we probably wouldn't have come here had we known that beforehand. Credit card sales shouldn't be the consumers issue. read more

I was visiting Denver and made a quick trip to Boulder for lunch. Found this place on Yelp and it didn't disappointed. Couple of things to know. You will have to go through an app to pay for parking. This place only accepts cash. They do have an ATM on-site, if needed. As for the food and beer selection. Both were great. I was torn between the bison burger and the junk burger but decoded to go with the Junk Burger. It was literally cooked to perfection (well done chef!). As for the beer, they had 18 to choose from including two gluten free options. I could decide so I went with a beer flight which allowed me to sample several in my typical range of beers. Definitely would come back and recommend to anyone making stop in Boulder. read more

First major thing you need to know - CASH ONLY! They do have an ATM at the back, but just come prepared. We stopped in Saturday night for dinner. This place is always packed. Luckily we got in on a sweet spot where the didn't have a line. I had the raspberry beer and date night burger. The date night burger is just the best in my opinion. Everything about it is perfection, from the date puree, to the bacon and melted goat cheese. Mmmmmmm mmmmm. Service was eh. They seemed too busy to like more attentive I guess. Chips are good but a little over seasoned in my opinion read more

Love this place. I've been going since I was a child and it's still top of my list for dinner/ lunch spots. Casual, laidback vibe with such friendly servers. The food is great with many options for vegetarian, gluten free, and others! read more

Service 10/10 Food 10/10 Ambience 10/10 on the Groovy scale. Piped in music- wants to make your body groove! Note: they only accept cash or check, but they do have an ATM onsite. We didn't know but worked out. From the time you enter you feel the friendly vibe. We felt very welcomed and at ease. I didn't take a photo of the tortillas soup because I was starving and it came out first, but OH MY GOODNESS! I wanted to order a bigger portion and forget the rest of the meal. Don't sleep on that soup- LARGE chunks of tasty, gently cooked beef. I was amazed at the flavor and gobbled it up before I even thought to take a photo. We both got the Basic Burger with cheese and fries. The fries are crunchy on the outside and tender on the inside. Just how I like them! The burger was SO JUICY! what a great place to visit when we come back to Colorado. read more

Fun spot on Pearl Street that's all Colorado. Almost late night diner vibes, but definitely a step up from that. I found the atmosphere sort of took me back to the 90s in a good way, and it was lively and fun on a Friday night. I got a black and bleu cheese burger and fries; fries were killer, burger was OK. Service was friendly and welcoming, as was the whole vibe of this spot. A little surprised to see they do cash only in this day and age, but luckily someone in our group had it covered for us this time around. They will let you know up front and it's spelled out on the menu as well. All in all, fun spot on Pearl St. to pop into and grab a beer and a burger. read more

This is a cozy, iconic spot in Boulder! It's giving major pub energy: no frills, great service, and important to note: only takes cash or check (but there is an ATM in the back). There's verrrryyy Colorado murals and paintings on the walls, quirky decor throughout, and a homey feel. Their menu is pretty standard American pub fare: I got the steak sandwich and it was pretty solid. The chips were delicious! They seem to be known for their beer, but I had one of the ciders available. That was refreshing and crisp! We left just as the live music started, which worked out because they were loud. I wouldn't necessarily run back to this spot or be at the top of my list to recommend in Boulder, but it was a cozy joint for American pub fare and brews! read more

Came here for lunch on a Sunday and had a nice meal!We were able to find a parking spot in a paid lot and walk around. We chose this restaurant to eat at because of the wide variety of foods! The 5 of us were able to be seated immediately. Inside was cute with a decent amount of seating and some seating outside too. The service was good. They had vegetarian and vegan options which was nice. They had unique bowls, grilled cheeses, sandwiches, and salads. We didn't realize they only took cash and check. I ordered the speakeasy steak and really enjoyed it! Bread was crispy and the sandwich was packed! I upgraded for $3 for fries and was happy I got them, they were very crispy! ~$!6.50 for the sandwich which i thought was a fair price. My friends also enjoyed their meals! I left very full and happy! Yum! read more

Great first time at mountain sun! I've heard about it for awhile and finally got to go. It's been around since 1993 so definitely a boulder must visit. The service was amazing everyone was super helpful and friendly. The steak speakeasy sandwich was sooo good I would definitely get that again. It's spicy though so keep that in mind if you're sensitive to that. The tofu sandwich was perfectly crispy and sweet with the honey added. The Greek fries weren't as crispy as I would have wanted but the combination of flavors was great with the Pom seeds and hot honey and tzatziki. Can't wait to go back! read more

Denver visits aren't complete without hiking in Boulder followed by Mountain Sun! The service is always excellent. Their staff seem to enjoy the work they do. The beers are great - something for everyone. And the hearty food is perfect for that post hike refuel. Suggestions - pollo asada burrito, vegan chili, black and bleu burger. With all of the choices for food in the area, we keep coming back. read more

No idea about the food and drink, but this place is WONDERFUL when it comes to events. I ran a unique event around Boulder and included MSP. Their team was very accommodating. If you're trying to get a lot of people together, this pub is delightful and very easy to work with. Look no further! read more

Nice Sunday afternoon lunch after a hike nearby. 4 of us came in and decided to sit outside on the sidewalk/patio setup. Service was great, came by to give us waters, take our orders etc. We were offered a free basket of fries, and while I don't like to complain about free things, they were a bit salty for our tastings (although it didn't stop us from finishing the basket). I really enjoyed my tomato bisque soup, and the black bean burger was okay. My friend did check about gluten free options and ordered the BLT because it was on gluten free bread, but then when it came out she double checked and they had to re-make because it wasn't on gluten free bread. Overall lovely lunch on Pearl Street. read more

Mountain Sun Brewery is one of those Boulder spots I keep coming back to. The food always feels home‑cooked in the best way - comforting, flavorful, and consistently satisfying. The staff is warm and genuinely friendly, which makes every visit feel relaxed and welcoming. The ambiance has that classic Boulder charm: lively but never overwhelming, with an overall atmosphere that just makes you want to stay awhile. And honestly, Southern Sun on the other side of town is every bit as good. Same great vibe, same great food, and even more relaxed - just a different neighborhood. You really can't go wrong with either location. read more

Tried 3 different IPA's landing on the hazy as my favorite. The nachos tasted very good, I do love some salsa on my nachos, but so much liquid on the bottom the chips were like noodles, but hey, it was still good. Service was top notch, they all take care of you so very little waiting at all. Comfortable atmosphere with some chill tunes playing. Definitely worth the stop. read more

Delicious food, cool vibes, great location! My friend and I stopped here on our way through Boulder after a local recommended it to us. So glad we did! It's located off Pearl Street, Boulder's most hopping area. We were able to find street parking close by, and it was cheap! First things first, it is CASH ONLY, so plan accordingly! There is an ATM on site, not sure of the fees, etc. When we arrived, it was pretty busy, but we were able to sit on the patio. The nice thing about the patio is that it's heavily shaded with umbrellas (which, admittedly, made snapping photos a tad tough for this foodie gal!) This place is quite interesting inside. The wall decor is cool but it has carpet and older looking tables, so that was different. It looked more like a diner/old fancy restaurant had a baby vs a brewery. This might be part of the vibe they're trying to achieve, but I'd probably go for patio seating every time! Our waitress was wonderful. She was super busy but checked on us often and we never wanted for a thing. We tried beer and it wasn't our fave, but we had been in the hot sun that morning so water hit the spot. We started with the nachos and they were BOMB! They're HUGE and the cheese pulls are outta this world. So good! For mains, my friend ordered the Date Night burger sub chicken and she really liked it. The chicken was a little small, but it was tender and the flavors were delicious. I had the Junk Burger (no mushrooms sub in caramelized onions). It was phenomenal! Highly recommend. So cheesy and tasty. I loved the roasted garlic mayo. I also love their fries and the availability of malt vinegar. Overall, Mountain Sun is a great spot for lunch and a beer. Honestly, if the inside decor switched it up a little/carpet was removed, I'd give it a full 5 stars, this was just super odd to us. Don't let that deter you, though, definitely stop by! read more

Mountain Sun Pub & Brewery is located right on the main street of Boulder (Pearl Street). They have a large selection of beers. Also they have pub-type food. I ordered the Blue Cheese Burger with fries. Overall good food, but my burger was a little underdone. Good overall selection on the menu though, and I've been here a few times. Please note they have a cash only policy. read more

One of the best hamburgers I've eaten in my LIFE! We visited here on a trip last week and I'm still dreaming of this hamburger! If I'm ever in Colorado again this place is a must! They only take CASH so tourists be ready!! read more

Came here for dinner and enjoyed the experience. They have some nice beers on draft (I really enjoyed the golden moose hazy IPA) and they serve a variety of traditional pub food. The interior has a "homely" feel and the servers are friendly. While their fries are phenomenal -- I ordered the bison burger and wasn't very impressed; perhaps their regular burgers are better. Prices are very reasonable for the quantity served. Definitely a good place to swing by for a beer, and perhaps a burger, if in town. read more

Business is CASH ONLY! To be fair, they warn you prior to taking your order - which I appreciated. Lucky for us we had enough. I don't normally carry much cash. Burgers, fries & chips were very good & not small portions. They provide small beer tastes free so you can decide what you want. Limited outdoor seating. Server was friendly. read more

Opportunity to Improve. Upfront was told parties over 8 have an automatic 20% tip added. I stated the service should warrant the tip. I was assured it would. It didn't. We were not offered refills on our waters until we were almost done with our meals. We asked for ranch dressing as we were served, it never came. We had to go to the bar and ask for some. We did discuss with manager. We allowed the tip to remain. Like I said, these are opportunities to improve. read more

Came here after a long day and it was a great way to end the night. They are cash and check only! The service here was great! Our server was very friendly and attentive. We ordered one of their specials - A burger with apple jam and brie, and I think there was arugula. It was so good! Their beef is something else, the menu states that the beef they use are vegetarian fed Colorado beef with no steroids or antibiotics. The quality came through and the beef was spectacular! It was cooked to medium which is my ideal preference and it was so juicy. I loved the combo with the brie, apple jam and arugula! My favorite meal in Boulder! Their burgers all come with fries, and they were nice, soft but crispy at the same time. They also have a huge variety of beers and you can sample them if you like. I would definitely come back here! It's great vibes and good food and drank! read more

A very friend inclusive modern day hippie kind of place. Food is delicious with simple menu. We split a Junk Burger which was fantastic. The homemade fresh chips that came with it were unique with subtle BBQ flavoring and not too salty. The tip is shared and the service is a collective effort team-based approach. We were treated respectfully by everyone. Note: CASH only but there is an ATM nearby. Metered street parking but it's a few spaces away if you're an out of towner looking for the meter! read more

The service was good and the burgers and beer were solid. Fries were oddly a little grey. Sorry, but $62 for two burgers, two beers, and two fries is wild to me. Charging extra for fries on an $18 burger is already wild to me. Also, having to withdraw cash from an ATM (credit cards not accepted) is a poor experience. I'm very surprised this place is reviewed as highly as it is. read more

This place was amazing! The atmosphere, the staff, the food-all of it!! My friend and I had burgers and my husband had some kind of sandwich. It was all delicious! They keep my water full at all times. They were attentive, but not too much, it really was the perfect amount of attention. They were engaging and answered questions and seemed happy to do so. I want one near me! I went to their site to recommend that they put one in the Springs. read more

Nothing but positive things to say about this place. The staff is friendly, I was there right at noon but it wasn't swamped (and they had the a/c cranked up when it was 90 degrees outside), my burger tasted delicious, and the fries were heaven sent. Note that it's CASH ONLY, though the ATM in the back only charges a $1 fee (in addition to whatever your bank charges). It's not "gourmet," but I'll never turn up my nose at a well made burger with delicious fries. Prices were also quite reasonable, in my opinion. read more

As far as the food goes, the french fries are exceptional! Get them with cheese on top you will not regret it. The hamburger was a good hamburger, but it was not as bodacious as I get expected by the description. But it was good. The staff was extremely accommodating and the crowd was great. The environment here is really nice for a date or for family. It's great for small, gatherings or large gatherings. I really enjoyed the vibe and I really enjoyed the hospitality. But here's where it gets Jenkee. I ordered a flight of beer. I ordered six. But only five came out and I was told they were out. However, the sixth came out after I started the flight. Not a big deal. But I had already tasted the entire flight in order. Then there was the flavor of each beer. I'll take it one by one. The Irish stout had a weird back flavor kind of like a chemical flavor not a natural flavor. The blackberry wheat was alright. I've had better Berry Wheat beers. But it's drinkable. Unlike its name, the Colorado Kind Ale was extremely confronting in its initial flavor. I think at the time of drinking it I said it was extremely abrasive. I don't think I even finished that one. The Spanish holiday sangria was also drinkable, but not exceptional. It was oddly bitter. And I love stouts. But the coconut cream stout tasted burnt. The best one was the Soul Flower Saison in my opinion. It's a little rich it's full bodied, and it feels like a treat. Well, I did not try every beer. And there may be some real golden award winning phenomenal brews at this brewery. But I did not find them on my flight. I think pretty much everything else was IPAs. If you go know that you will be well taken care of. Absolutely get the french fries. They are a super treat. read more

Went to Mountain Sun with a friend after a hike in Boulder and it fulfilled all my needs - a crisp beer and delicious bite to eat. The menu has options everyone including a great variety of beer; they offer free tasters if you're unsure which one you might fancy. The staff was extremely friendly. The restaurant isn't overly large but there was not a wait when I went. They have indoor and outdoor seating - I recommend outdoor as it is in the heart of Boulder and who doesn't love a good patio beer? They do not accept credit cards so you have to pay with cash or check, but there is an ATM inside. They also offer the option to take the check home and send $ after the fact - they believe in humanity. read more

There's such a cool vibe to this spot! Normally I'd be irritated with a restaurant being cash only, but the "karma" policy of trusting others to mail-in a check later-on is awesome (there is an ATM for those who don't have cash and are able to pay during their visit). My bison burger was everything! I'd order it again and again. You could taste the freshness of the bison and it was cooked so that the meat melts in your mouth. It had the addictive quality of a fast food burger, but the freshness of fine dining -- who wouldn't want that?! The servers all share tips, so the entire waitressing staff is willing to help and checked-in regularly. I had a beer which was good (nothing extra special) but we were also given a free margarita which was made by the bartender-in-training. read more

Stopped in here after a hike -- Mountain Sun is more of a Restaurant than a brewery. Every table was full around noon on the weekend, but the tables turn fairly quickly.

Good selection of beers -- all quenched thrust after a nice day hiking. read more

The date night burger was very good. Perfectly medium, crunchy slaw and apple. Fries are mid. It's nice that everyone does every job but that also means there were 4 people working with us. Someone to take our order, someone to drop the beer, someone else to drop the food and another person to drop the check. The beer was wonderful. They have a happy hour from noon to 5:00 pm daily. We already ordered when we noticed. Just like another neighborhood bar. Nothing fancy, nothing exciting, gets the job done when you're hungry. Burgers were $17+ read more

What a great college town eatery. The service is fantastic- 5 stars. Great conversation and friendly staff all around. The beer - 5 stars. All made in house! Casual and comfortable dining with tables and booths. Family friendly. Great menu with lot of great sounding options. I went with the grilled Reuben special and it was OK at best. Cheese fries were pretty good. I would definitely return but would hope for a better food experience. Cash only, team service and shared tips. read more

After an exhausting but fulfilling day of picking out a Christmas tree, my family and I were ready for a hearty meal. Mountain Sun seemed like a great choice halfway through the drive home, and we got the last large group table available. There were 7 of us total. Customer service is unrivaled. I'd come back just for the positive (Boulder) culture and vibes. For food, I had the S.O.B. Burger (bacon, Cajun seasoning, roasted hatch chilies, jalapeños, pepper jack cheese, lettuce, tomato, onion) which was quite tasty. I thought the fries were overdone and undersalted, not enough to send them back, per their promise. Everyone else seemed to enjoy their food too, including the kids who can be picky eaters. We had to park on the street a few blocks away, which is typical for Pearl St in Boulder. There was some sort of holiday parade getting ready, making it a more magical experience. Love watching the crowds around this part of town. Would especially want to visit Mountain Sun when the weather is warmer so I can enjoy beers on their front patio! read more
