As far as diners go, Kleifelds is as Old School as you can go. This is a no-nonsense, busy diner, not a new restaurant trying to go retro. My dad used to eat here 30yrs ago and it hasn't changed much.
Their omelets are tasty and hash browns are excellent. I especially like the quick service and GREAT prices!! A cup of coffee: $1.50. The most expensive omelet on the menu: $5.49.
Check 'em out while in Willoughby!
