Protein Bar Kitchen is a lifestyle application developed by PB Restaurants LLC that allows iPhone users to order healthy food from the comfort of their own homes or on-the-go. With this app, you can easily order delivery with real-time order tracking, or order ahead for easy pick-up or pay in-store with a tap.

One of the best features of the app is that new users receive a FREE shake after the first purchase of an entree or shake. Additionally, you can earn $8 for every $88 you spend, and easily modify your order to make it your own. You can save and re-order your favorite meals, view nutrition and allergy information, and get exclusive access to deals, discounts, and previews. Finding the nearest PBK location is also a breeze with the app's GPS feature.

Overall, Protein Bar Kitchen is a great choice for health-conscious iPhone users who are looking for a fast and convenient way to order healthy food.
