I have been going to the Blauvelt Diner for the past 8 years. The staff is friendly, and I have gotten to know a few of them. I am Greek so I know the owner as well. The food is excellent. The service is good too. The environment is old fashioned which is the way some people like myself like it to be. So definetly go check out the Blauvelt Coach Diner on 303. They open 24 hours.
Pros: open 24 hours, good parking, inexpensive
Cons: no smoking section
