Actually Jealous of Boise

Best vegan burgers I’ve ever had from a non vegan spot. The best part is the cost. $10 for a single (1/4 lb impossible) or $12 for a double (1/2 impossible) both with vegan cheese and vegan special sauce. The coconut based shakes rip (and do taste like coconut if you don’t like that). The vegan nugs taste like impossible and were good.

So Dang Good!

I was excited when I saw this place with a Vegan burger AND Vegan shakes! Had to try and it was so so good. Hit the spot for sure. They also have vegan nuggets I don't get to try but wished I had.

So insanely good

They have so much all of which is vegan. Burger, cheddar and pepper jack cheese, grilled cheese, chicken nuggets, fry sauce, shakes (in so many flavors), and fries.

I go here whenever I am near, they do not play around with their vegan menu.

Pros: Options, Vegan cheese and fry sauce, Always get my order right

Cons: Longer wait for vegan stuff

Thank you god for Big Bun

Seriously, I’m so thankful for this place. Vegan burgers, nuggets, and damn good vegan shakes. The strawberry shake is my favorite, and the chocolate kinda reminds me of a frosty.

FAVORITE BURGER & NUG SPOT

Big Bun is so [censored] good!! Vegan burgers, cheez, milkshakes, and nugs?!
Plus the new location on Glenwood & Chinden is even closer to me. If you haven’t been yet, you’re missing out!

Impossible + Vegan Shakes!

I love that they have vegan options, including milkshakes! The Impossible burger is delicious, their fries are crispy, and the vegan fry sauce is so good! They have a covered, heated outdoor patio for winter dining as well.

Impossible Burger

This place knows what they’re doing. They cooked the Impossible Meat the correct way and add Vegan Pepperjack. Loved it.

Tasty Burger

Amazing impossible burger with super melty vegan cheese and vegan special sauce. They also have a ton of vegan desserts (milkshakes, cones, and more). I would pass on them unless you love coconut as they have coconut base and taste very coconut forward.

Great Impossible Burger

These guys have an amazing impossible burger that you don’t have to “hold the toppings.” They have vegan Mayo, vegan fry sauce, vegan cheese. I haven’t tried the shake, but if you are wanting a greasy, vegan burger and fries, this is definitely the best!

Pros: Vegan cheese, You don’t have to order it dry, Greasy goodness

Cons: Drive through can be pretty busy (but moves fast)

And a pup cup???

You could say that my experience resulted in a slew of emotions. Bewildered and amused at the question of whether or not I also wanted a pup cup (a tiny ice cream cone with a milk bone garnish). Thankful and possibly spiritual at the gooey bites of my vegan grilled cheese. Pure anger and disappointment as a fly landed on the last bite of my burger.

I would sell my soul for big bun

This place is dangerously delicious. All of the classic fast food grub in vegan form. I usually get a vegan burger and the vegan fry sauce is a must. Tots & fries are good too! Like others have said the Shaka are made with coconut so if you like that flavor then they are good. Their vegan ice cream cookie sandwich is also💥. Staff are great and helpful every time we go (which is often lol)

Pros: Lots of options, Summertime huckleberry shake is great! , Locally owned!

Great Burger!

Great Burgers here. A friend took me here for vegan burgers since I hadn't tried it, and it did not disappoint. Got mine with no cheese, the gluten free bun, and the vegan sauce.
Some of the best food I've eaten in a while, and will definitely be coming back!

Pros: Great Burgers, fries, and sauces!

Cons: Kinda expensive.

Vegan Surprise!

I have lived in Boise for 30 years and never would've thought to try this burger place for a veggie burger. After reading a review here, we thought we'd try it. Wow! What a surprise! Ordering vegan was super easy. They have a separate vegan menu. It's a burger place, so you're not getting a variety of vegan options, but they have a great Impossible burger with vegan sides, vegan sauces, vegan cheese. They even make vegan shakes and ice cream. If you're in the mood for a classic fast-food vegan burger with fries, this is the best place for sure.

Pros: Easy vegan ordering, Great Vegan options, Fast food

Perfect Burger and Fries

I’m not really sure how to expand on this further. I feel like the title of the review says everything it needs to say. Impossible burger with vegan pepper jack, a side of fries, vegan fry sauce and a vegan snickers shake for dessert.

I think what makes this so special is you’d never guess this spot had vegan options best off look and location. All vegan food is clearly marked in your to-go bag.

Pros: So good , Pretty cheap

Cons: Lots of waste

Impossible burger done right!

This was the best impossible burger I have had! A perfect classic burger and crispy tots. They even had vegan fry sauce! I had my burger as it comes with vegan pepper jack cheese. For a drink I chose blueberry lemonade which was perfect because it was 102 out! Highly recommend. Had to try the vegan milkshake to go. It did not disappoint.

Pros: Burger was cooked perfectly , They know what vegan means.

Excellent!

What a find. Had the impossible burger with Dayia pepper jack cheese. Medium fries with vegan fry sauce. A MUST if you're craving a burger. Friendly staff and military discounts. I'd give them 5 stars for making us happy.

Awesome!

Me and my husband were heading back home on road trip (14 hours driving) and we stopped to get some lunch at this place and we were very satisfied! We had impossible burgers, fries, and shakes ( I love it!!!!!) They have a separate vegan menu on their online order website, made it super easy for me to order!

Pros: Lots of options, very tasty burger, vegan sauce!

Six Stars!

I was only allowed to give it four stars because it isn’t fully vegan, but the vegan options are delicious! Great service and delicious food!!

Yum!

This is the place I go when I want to indulge in junky food that is bad for me. Always get the impossible burger with vegan cheddar, jumbo fry, jumbo onion rings (best onion rings I've ever had in my life, just perfectly crisp with a soft onion inside), lots of vegan fry sauce, and a vegan strawberry shake. My daughter and I go into a food coma every time we eat here but its so worth it. The staff is super friendly as well.

Yummy!

We had heard Big Bun started serving the Impossible burger and had dairy-free milkshakes so we had to check it out! It was my husband’s birthday so we wanted something fun and tasty. He got the impossible burger with regular cheese, I got mine with vegan pepper jack cheese. The vegan fry sauce was delicious and I was pleased with how yummy the burger was.
We also ordered vegan milkshakes. I got blackberry and my husband got mint chocolate chip. They’re made with coconut milk ice cream, so you can taste the coconut, but they were still good! It had been so long since I had a milkshake of any kind so I was happy I finally had an option!

Pros: Vegan cheese for burgers, Vegan fry sauce , Vegan milkshakes

Cons: Not many options , Only one location
