I absolutely love hardline coffee. It is the most warm and welcoming space in Sioux City. They serve a very high quality product for a reasonable price. Weather it’s hanging out with friends or a business meeting Hardline is my first choice every single time ❤️

Definitely not 5 star, but not the worst. Coffee was mediocre at best. Ordered a quad Americano with steamed breve. My coffee was not hot. The little art studio in the back was kind of cool. Offset the mediocre coffee a bit, but not enough to go back.

This spot is super cozy and filled with warm energy. Many seasonal drinks were sold out, but I didn't mind. I got the fireside mocha and the caramel swirl bagel with plain cream cheese, and both were super yummy! I was fearful of the cayenne spice in the mocha, but it added amazing flavor that wasn't overbearing! I loved it.

Delicious coffee drinks and baked goods, Hardline offers a comfortable space with wonderful service. Coffee is roasted on-site, and all syrups are homemade. Vegan and gluten-free options grace their menu.

Waited about 30 min for our coffee this morning the dude behind the counter must've been doing too many hard lines before coming to work! He was completely out of it! At one time he stood at the counter and just stared at us for a good five minutes. But I will say the coffee was ok and the muffins slapped!

The coffee choices were unique and they also had your tried and true standard coffee choices. The service was excellent and the atmosphere was charming and eclectic. Great environment for kids as well and a great place to support local artisans as they display their work and offer it for sale.Dietary restrictions: They offer multiple milk alternatives and vegan options.Kid-friendliness: They have an art station, a reading nook, board games, etc., in an area where you can easily monitor your children while enjoying your coffee.

Such a neat vibe! I got the coffee flight... been dying to do this somewhere and it is such a fun way to sample coffees. Was a bit more bitter than I'm used to but still very good! Beautiful art gallery is connected as well.

The most unite lattes I've ever had has been at Harline. I've had a rose petal latte, and today I got the Saturday morning Cartoon latte. Very creative!
