White Castle Restaurant was forced to temporarily close it first Las Vegas strip outlet on opening day this week just to allow its workers to "catch their breath" after demand for their "slider" burgers proved to be nonstop.

"Due to overwhelming demand White Castle Vegas is currently closed for maintenance and to restock," officials tweeted on the company website, roughly just 24 hours after the store opened at 2 p.m. Tuesday.

Company vice president of government and operations Jamie Richardson later claimed the Casino Royale-located store was moving a record-setting 4,000 burgers per hour over the first 12 hours they were in operation.

"Las Vegas is the epicenter of all craving," Richardson told the Las Vegas Review-Journal. He added being forced to close its doors for such considerations is "a historic first" for the 94-year-old Columbus, Ohio-based burger chain.

Richardson stressed the restaurant never ran out of their famed 2-by-2-inch burgers, but chose to briefly shut it down to do some cleanup and other maintenance work.

At around 3 p.m., company officials were back online, tweeting: "The White Castle Vegas doors are back open and we're back in business. Thank you Vegas for your patience."

Richardson later chimed, "we didn't think it was possible, adding the company's nearest Las Vegas location sits some 1,500 miles away in Missouri.

White Castle Las Vegas' very first customer is reported to have waited in line for more than three hours for the honor of ordering a double cheeseburger, french fries, onion rings and a shake. All day long Tuesday, the line at the restaurant stretched around the nearby Best Western Plus Casino Royale on Las Vegas Blvd.

Prior to opening the 24-hour eatery, White Castle officials hosted several job fairs across town in hopes of shoring up for all the business they were hoping for. The company previously operated White Castle food trucks across town and patrons reportedly waited in line as long as four hours just to be served.
