Protein Bar & Kitchen

Protein Bar & Kitchen at Chicago O'Hare International Airport’s Terminal 5 is a bright, modern fast‑casual spot designed for travelers who want a nutritious boost before a flight or during a layover. Open from 5 am to 11 pm on weekdays and 5 am to 9 pm on weekends, the restaurant mirrors the airport’s schedule, offering breakfast classics like the Egg‑White Power Wrap and a tropical Acai Bowl topped with fresh berries, granola, and a drizzle of honey. Signature items include the 20‑gram “Power Protein Shake” blended with whey, banana, and almond milk, and the Keto Chicken Caesar Wrap that packs lean protein and crisp romaine without hidden carbs. Vegan diners can enjoy the Quinoa‑Black Bean Bowl, while gluten‑free guests appreciate the customizable salads that list every ingredient. The interior features sleek stainless‑steel counters, high‑top seating, and large windows that overlook the bustling terminal, creating an energetic atmosphere perfect for quick meals or a relaxed coffee break. Guests earn points through the PBK Rewards app, unlocking the Thursday $5 shake special and other exclusive deals. Although the O’Hare location is walk‑in only, online ordering through the website or mobile app lets travelers place orders before security and pick up at gate M21. The venue also supports corporate catering for nearby hotels and conference centers, delivering fresh platters that cater to keto, paleo, vegan, and vegetarian diets. Whether you’re a frequent flyer, airport employee, or a Chicago local seeking a protein‑rich lunch, Protein Bar & Kitchen delivers fast, flavorful, and health‑focused food right in the heart of the world’s busiest airport.
