History

Kona Grill's roots lay in Sushi on Shea, a Scottsdale, Arizona, sushi concept opened in 1994. Michael McDermott developed the broader Kona Grill format by adding substantially more American menu items and emphasizing a contemporary restaurant environment. The first Kona Grill opened on September 18, 1998, at Scottsdale Fashion Square. The resulting concept was designed to occupy the middle and upper-middle portion of the casual-dining market, combining American food, sushi, cocktails, and a modern atmosphere with Hawaiian-inspired visual and culinary cues. McDermott sold Sushi on Shea in 2002 and focused on growing Kona Grill. The company expanded its domestic restaurant base during the 2000s and became publicly traded on August 16, 2005, through an initial public offering on the NASDAQ. The offering was priced at $11 per share and raised $28.8 million. By December 31, 2005, Kona Grill had nine restaurants, giving the company a larger base from which to pursue national expansion. Growth continued into the 2010s. By 2014, Kona Grill had 26 restaurants across 17 states. The company reported same-store sales growth in 14 of the previous 15 quarters, including a 6.2 percent increase, and characterized its performance as ranking in the top quartile of the casual-dining segment. The brand's format depended on menu breadth: guests could choose from conventional American dishes, sushi, and cocktails, allowing restaurants to serve different occasions and preferences under one brand. Kona Grill began international franchising in 2017. Its first international franchise location opened at Fashion Drive in Monterrey, Mexico, in August. A Dubai, United Arab Emirates, location followed at Al Seef in November, and a Vaughan, Ontario, location opened in December. Reference material later described the company as operating approximately 40 restaurants in 23 U.S. states, in addition to three international franchise locations, although the chain's footprint was affected by subsequent closures and restructuring. The company's financial position deteriorated in 2019. On March 4, it retained Piper Jaffray to investigate a merger or sale. Shawn Hassel joined the board on March 21 as chair of the Strategic Alternatives Committee, and Executive Chairman Berke Bakay resigned on March 27. Kona Grill filed for Chapter 11 bankruptcy protection on April 30. Restaurant closures were reported in several markets, including Arizona, Texas, Hawaii, Puerto Rico, and Virginia. The bankruptcy process led to the sale of 24 polished-casual restaurants to Williston Holding for $20.3 million after approval by a federal bankruptcy court. Separate reference material identifies a $25 million acquisition by STK Parent, associated with One Hospitality Group, in 2019. These transactions and the restructuring created ambiguity about the legal and operating continuity of the original public company versus the continuing restaurant brand. The supplied material does not establish a definitive current store count or operating status, so Kona Grill is best documented as a brand with a disrupted corporate history and an unresolved present status.

Products and positioning

Polished-casual, contemporary dining that combines American cuisine with sushi and cocktails in a Hawaiian-influenced setting.

  • Restaurant menu · 1998

    American cuisine

    Kona Grill's American menu formed the broad base of its casual-dining proposition. The concept was deliberately created with more American-themed offerings than its Sushi on Shea predecessor, allowing the restaurants to serve guests looking for familiar entrées, appetizers, and shareable dishes alongside the brand's sushi selection.

    Sushi and sashimi

    Sushi was central to Kona Grill's identity and connected the chain to its predecessor, Sushi on Shea. Restaurants incorporated a sushi-bar offering into a wider American casual-dining format, helping the brand differentiate itself from conventional casual restaurants while retaining a broad menu suitable for groups with different tastes.

    Cocktails

    Cocktails and other bar offerings complemented Kona Grill's food menu and contemporary restaurant environment. The beverage program supported the brand's positioning as a polished-casual venue suitable for dining, social occasions, and evening visits.
