Building a
Global Street Food Brand from the Ground Up

Doner & Gyros was envisioned as a fast-growing, franchise-ready concept designed for rapid expansion. The ambitious launch of four outlets simultaneously was made possible through robust operating systems and a strong, capable team. RSI’s involvement spanned the entire journey: from brand conceptualization and identity development to interior design and the creation of scalable operations critical to the brand’s long-term success.

Positioned as an affordable, healthy, and flavorful offering, Doner & Gyros combines the best of Berlin and Chicago street food cultures. The brand specializes in generously portioned Doner and Gyro sandwiches, prepared live in front of customers, a distinctive element that adds both transparency and excitement to the dining experience. This interactive service model empowers guests to customize their meals, choosing between Doner or Gyro styles, sauces, and fresh ingredients, adding an ‘experimental’ flair to every visit.

We chose RSI because of its extensive restaurant industry experience and proven track record of successful projects. Our meeting with Gabrielle reinforced our decision as we witnessed her passion for her work and expertise. By selecting RSI, we have gained valuable insights into the local restaurant industry in the UAE. This has been helpful in refining our restaurant concept and identifying the optimal location for its establishment. The team at RSI demonstrates tremendous expertise. We appreciate their efforts in taking the time to truly understand our business, industry, and project objectives. They have leveraged their knowledge and skills to design and implement the best possible solution.
Sabina Saldanha, Samakna
We chose RSI based on the many successful restaurants they helped launch. RSI assisted us with Menu Engineering and Staff Training. Each service provided by them was excellent – the tastings, exploring different ingredients, learning the secrets behind assembling burgers, and all the smallest of details. RSI has always been swift with their response and understood every task clearly while meeting all project deadlines. We would definitely recommend RSI for being very supportive, insightful, patient, and professional and for helping us through our journey.
Alya Alkaabi, Monkit AUH
We were looking for the best restaurant consultancy firm in the UAE and Restaurant Secrets Inc. caught our eye. Our journey with RSI started with a simple query, and their swift response was a good indication of how well the company was structured. With RSI, we developed the concept of our brand new QSR business and also a strong, potential long-term partnership. We loved the result of their Menu Development service. The team ensured the project met the set timelines with timely delivered milestones throughout the project, along with flexibility in accommodating our extra last-minute requests. I would recommend RSI without hesitation, especially Gabrielle F. Mather for treating Nine50 as their own business and for doing everything they could to make it successful.

I chose to work with RSI due to their vast experience in the field and that they have worked on many great projects before. The service I received from RSI was excellent. Everyone that we worked with was very helpful, friendly and easygoing. From the first consultation with Gabrielle, she was very interested in the concept, she was able to give me a clear picture of what we needed. She offered valuable advice, was a great listener and took everything I said into consideration. Chef Brian was very knowledgeable about all items we were looking to develop, he trained our team members and made everything smooth and comfortable for everyone, we also worked closely with Nuwan in the baking section, he even visited our outlet in order to offer further training. With his help we were able to perfect the bread items. He was very resourceful in his craft. I would recommend RSI to anyone looking for help with their menu engineering as they made the process really smooth and the results are great!

I previously worked with RSI for an older project that I had done, their level of attention and professionalism is one of the reasons I decide to use them once again for my latest project. I found the techniques used to develop my new menu interesting and was pleased with how special our menu ended up being. They are great at listening to the client’s needs and care about the identity of the brand, they are also great with the guidance they give to the clients during the process. The consultants made me feel at ease and I was happy with the support I received.
