What our guests are saying
Recently renovated but this diner has been around forever. There are a ton of seats, so even when it’s busy, you’re not stuck waiting around. Lots of options to choose from and the portion sizes are plenty.

My son wanted to take me to this place. He used to frequent here with his mother, who is no longer with us. He's been asking me so today we went and it was such a wonderful experience being there with him and listening to his memories of him and his mother...the atmosphere was very nice...not crowded.
