restaurants. Within one week, we modified operations at 15 locations to add take-out only service. As restrictions were lifted over the next few months, wewere able to gradually reopen more restaurants at reduced indoor dining capacities and we also started offering outdoor dining at certain locations.
To support our employees during this challenging time, we continued paying normal payrolls to all employees through April 5, 2020 and toall kitchen employees through May 9, 2020. After those dates, we furloughed most employees but continued to pay store managers and key kitchen staff throughout the periods when their respective restaurants were temporarily closed. We alsocontinued to pay the employee portion of all furloughed employees health insurance through July 31, 2020. As our restaurants reopened with expanding capacities during late spring and summer of 2020, we were able to invite back many of ourfurloughed employees.
In response to the ongoing pandemic, we prioritized actions to protect the health and safety of our employees andcustomers. We increased cleaning and sanitizing protocols in our restaurants and implemented additional training and operational manuals for our restaurant employees, as well as increased handwashing procedures. We provided each restaurant employeewith face masks and gloves, and required each employee to pass a health screening process, which included a temperature check, before the start of each shift.
The temporary restaurant closures and the reduced capacities at the reopened restaurants caused a substantial decline in our sales. In lightof the challenges posed by the pandemic, we focused on maximizing our restaurant dining capacity by adding temporary outdoor dining at certain locations. Beyond prioritizing actions to help assure a safe environment for our employees and customers,we worked hard to maintain our operational efficiencies as much as possible to preserve our liquidity.
Although we temporarily paused ournew restaurant opening plans during the pandemic, our long-term growth strategy is to continue to open new restaurants in locations that we believe will achieve profitability levels consistent with ourpre-pandemic experience. During 2022, we opened three new restaurants and we have nine new restaurant locations with leases that have been signed. These locations are in Kapolei, Hawaii, Fort Lauderdale,Florida, Chandler, Arizona, Westheimer, Texas, Seattle, Washington, Jacksonville, Florida, Dallas, Texas, Maui, Hawaii and Cerritos, California (at which we opened a new restaurant on April 4, 2023). We currently expect to open six or sevenadditional locations during the rest of 2023. Future sales and profitability levels of our restaurants and our ability to successfully implement our growth strategy in the near term, however, remain uncertain, as the full impact and duration of thepandemic continues to evolve as of the date of this prospectus.
