In 2009, we opened our doors at a very small Chicago storefront with a very big idea. Instead of fast food, we’d serve fast fuel: shakes that were delicious, nutritious, and protein-packed.
It was a success from the start but quickly became something even bigger… a game changer. We saw what was happening and got excited. Let’s keep going. So we discovered quinoa and expanded the menu to serve a full selection of high-protein salads, wraps, and bowls customizable for all diets. Every body loved it. The all-day power of protein grew in popularity. We all started eating, feeling and moving better. It’s all good.
All these years and successes later, we never forget where we came from.

For the amount that you pay for the food, you would think that the quality would be superb, however I was disappointed by the brown leaves and carrots in my bowl. Also the chicken was just okay, not anything special and didn’t have a lot of flavor. I did like my smoothie though, this might be a better place for protein drinks rather than food/salads

No stars for the service and atmosphere as I did grub hub. But absolutely delighted with the order experience! Came faster than I was originally told, the food was delicious as all get up! And unlike the last few order outs I’ve experienced elsewhere they supplied us with utensils and napkins! Top notch!

The spring protein bowl I ordered was large, fresh and delicious. The service was prompt and employees were polite and friendly. (An added bonus, they had the cleanest, most sweet-smelling public bathroom I’ve ever seen)

Mobile Order experience is super easy! When I walked in, it smelled amazing. Today was only a smoothie order but can’t wait to try something for lunch! Smoothie was deliciously healthy. It was prepared quickly and correctly and everyone who I spoke to that worked there was well knowledged and very friendly.

Protein Bar consistently overperforms, and never disappoints. From the quality of the food and healthy ingredients, to the service, this place is A+. Although I have found all of Protein Bars locations to be consistent, the staff at Oakbrook Terrace standout. They are professional, courteous, and prompt, and the restaurant is always clean

So so good! I got the salmon Cesar and my friend got the Sonoma salad. All the ingredients were fresh and delicious!

A little expensive for the amount of food you get. I do love the spinach pesto quinoa bowl. The smoothies are also expensive and I prefer to make mine homemade. It’s cheaper and more delicious.

Ordered two salads to go, $26 total, one of which was supposed to be Harvest with roasted veggies. But it ended up missing the roasted veggies and had some bad lattice (which is not acceptable for a salad place). Also, the salad looked nothing like the salad in the picture. And…..it cost nearly $15 w/chicken substituted for salmon. Restaurant refunded the money. But I would have rather had a good salad. A little sad.
