Secret Burger Kitchen has signed leases for three new restaurants in Renton, Lynnwood, and Covington, Washington, and is now granting territories to qualified, well-capitalized multi-unit operators. The new locations are under development and will bring the chain from three operating restaurants to six.
This announcement marks the next step in the brand’s ambition to build a national, culture-driven burger chain. Secret Burger Kitchen began inside a Tacoma hotel kitchen and now operates in Tacoma, Seattle, and Kirkland. The ownership group is continuing to invest in new restaurants while opening an opportunity for experienced operators to help establish SBK in additional markets.
Secret Burger Kitchen’s fresh Angus chuck smash burgers use seasoning beyond salt and pepper, with subtle Punjabi influence designed to create a crave-worthy, umami-rich first bite. Wings, loaded shakes, and interactive sauce syringes extend the meal. A broad, high-energy soundtrack, expressive surroundings, and attentive hospitality make SBK a fun dine-in destination with something for everybody.
The company has funded the restaurants and brand development without outside investor capital. The three operating restaurants and franchisor are debt-free. Douglas Fry, David Bloom, and Brad Haley advise Secret Burger Kitchen across operations, development, and marketing. The next three locations will extend Secret Burger Kitchen’s own capital commitment and give the organization more opportunities to refine the operating model as it grows.
Secret Burger Kitchen is looking for experienced multi-unit groups to evaluate a brand with operating restaurants, a defined food and guest experience, and an expanding footprint. It’s seeking partners with strong teams, local market knowledge, and the capital to develop thoughtfully.
The most important introduction to SBK, however, remains the burger. Fresh Angus chuck meets the grill, develops a seared crust, and comes together with melted cheese, the brand’s own seasoning, and house-made sauces.
Founder and CEO Paul Sandhu’s mother’s approach to American and Italian cooking is on display, using the spices she knew from their Punjabi upbringing, which shaped how he thinks about flavor. Sandhu carried that perspective into SBK when, along with his nephew, Mandeep, they began developing the food inside a Holiday Inn kitchen in Tacoma. That origin gives the flavor an honest story, and the original restaurant remains part of the business today.
The influence is integrated into a familiar American smash burger. Secret Burger Kitchen wants the guest to enjoy the bite and crave another before thinking about its backstory. It’s a clear distinction: the culinary story is depth of flavor with subtle influence.
Wings give guests another reason to visit and groups more ways to order together. Secret Burger Kitchen’s eight flavors span sauces and dry rubs, including Buffalo, Lemon Pepper, Garlic Parmesan, Hot Honey, and Caribbean Jerk. Plant-based availability and a bowl option help accommodate different preferences at the same table.
Loaded shakes make dessert part of the occasion. Sauce syringes allow guests to add flavor themselves, giving the meal a recognizable interaction and a moment worth sharing. These details create ways to participate in the experience while keeping the quality of the food at the center.
For an operator, it’s a proposition to evaluate across different occasions: a burger-and-fries lunch, a wings visit, a meal with friends or a family outing. More accessible meal choices are part of the chain’s effort to make Secret Burger Kitchen fit ordinary weekdays as well as larger occasions.
Burgers, wings, and shakes give a new customer an immediate understanding of what Secret Burger Kitchen serves. The seasoning, sauces, and complete visit provide reasons to choose Secret Burger Kitchen. That is the product thesis behind the company’s national ambition: familiar categories carrying a distinctive flavor and experience that a local team can introduce to its community.
Secret Burger Kitchen’s restaurant is a destination where people come to eat, enjoy the environment and service, and have fun together. A great meal is the foundation. The room should make someone glad they chose to have it here.
The music mixes Top 40, Latinx, old-school selections, country, rock, and some world music. Hip-hop is part of that broader mix. The purpose is good energy and something for everybody. Street art and streetwear shape the visual identity, while music and hospitality help people of different ages and backgrounds feel welcome.
Sandhu’s hotel background shapes how the organization thinks about service as well. Its philosophy is that the kiosk handles the order, and the human handles the human. The transaction can be digital while the welcome remains personal.
Secret Burger Kitchen’s front-of-house “Vibe Ambassadors” help guests, deliver food, check accuracy, take ownership of mistakes, and give a genuine thank-you.
For an operator, destination appeal creates a specific opportunity to investigate: whether the food and experience earn deliberate visits, group occasions and repeat business. The dining room is an active part of that proposition. Secret Burger Kitchen wants guests to leave remembering both the burger and how it felt to spend time with the brand.
Secret Burger Kitchen’s packaging and content extend the restaurant’s identity, too. The brand’s Instagram audience exceeded 55,000 followers in early October. That gives Secret Burger Kitchen an audience to engage as the footprint grows.
Local relationships matter. Schools, athletes, artists, and neighborhood organizations are examples of the communities Secret Burger Kitchen wants each restaurant to engage. A capable local operator can help make the brand part of daily life in a new market.
The ownership group has financed the restaurants and brand development with its own capital. All three operating restaurants and the franchisor, SBK Burger Co LLC, are debt-free. The restaurant businesses are held in separate operating LLCs. Secret Burger Kitchen has not taken outside investor capital.
The leases in Renton, Lynnwood and Covington extend that commitment. These openings will take Secret Burger Kitchen from three restaurants to six and give the team more operating experience across sites and managers. Secret Burger Kitchen’s own ownership team carries the responsibility for the food, service, training and opening execution.
Fry advises on operations and organizational development, Bloom on growth and development, and Haley on marketing, positioning, and the guest experience.
Fry brings experience as the former Subway North America president, Haley from Dave’s Hot Chicken and IHOP, and Bloom from Quiznos and Capriotti’s. Haley described SBK as having a “unique, very compelling and scalable proposition.”
Over the past two years, Secret Burger Kitchen has developed procedures, training materials, and brand standards for kitchen and front-of-house roles, shift leaders, assistant managers, and general managers. Training moves through learning, practice, and demonstration during service. Preparing managers to teach others is essential to opening more restaurants.
Secret Burger Kitchen’s standards follow the meal from burger construction, crust, sauce placement, and temperature through modifiers, sauces, completeness and packaging. “QSCV” means Quality, Service, Cleanliness and Vibe. Those standards turn the guest promise into work a team can perform each shift.
Secret Burger Kitchen recently reduced the printed box-combo section from eight choices to four and removed tender-based builds. Wings, plant-based availability, and a bowl option remained. The aim was clearer meal selection and more focused kitchen execution. It is a specific example of how the company is refining the model rather than simply adding locations.
Secret Burger Kitchen’s next openings will sharpen trainer preparation, manager coverage, station readiness and post-opening support, the company said. It will evaluate more accessible meal choices through visits, contribution per order, and execution. Those operating decisions connect the brand’s personality to the economics that matter to a partner or investor.
The case for taking a closer look at SBK, Sandhu added, is the combination now in place: distinctive food, a fun dine-in experience with broad appeal, three restaurants to evaluate, three further leases signed, ownership capital committed, and experienced advisory support. “We believe those ingredients create an opportunity to build something meaningful in the burger category,” he explained.
“For multi-unit operators, the appeal is the chance to help establish a developing brand in a market they understand. For investors, the question is whether this product and guest experience can support an enduring restaurant business at greater scale. Both conversations begin with the operating restaurants, the leadership team and the evidence behind the model,” Sandhu said.
Secret Burger Kitchen is now granting territories to qualified, well-capitalized multi-unit operators. “Our FDD is ready. We are seeking groups with strong local teams, real estate knowledge, manager-development capabilities and the resources to support thoughtful growth,” Sandhu continued.
Secret Burger Kitchen intends to develop local clusters, considering customer fit, density, access, site economics, and operating support. Partners would work directly with leadership as the company establishes new markets. Territory terms and development commitments will be addressed through the evaluation and agreement process, it said.
