The Tick Tock Diner on Route 3 in Clifton will be closed for renovations beginning Monday.
The 24-hour diner will likely be closed for four to six weeks as they make some renovations -- the first in 25 years.
The plan calls for a new interior design, new furniture, new bar and an upgraded kitchen.
The iconic neon Tick Tick sign outside isn't going anywhere, but will instead be re-installed higher above the diner.
The Tick Tock has been around since 1948, and is slated to reopen in mid to late-October.
