Food was prepared correctly and served hot. Server Alfredo was very polite and attentive. Staff was super nice to my daughter and gave her a rainbow cookie! Can't ask for much more. Manager/owner was friendly unlike neighboring competition.

It was a very nice diner on Long Island. It's been decades since I've been back up North and it was nice to see diners, again. They are rare in Florida. We had a brand new server. She was trying her best, as I understand being new to a position is difficult, at first. I'm in the hospitality service, so I understand. The diner was very beautiful.

Warm welcome from the hostess and friendly competent waitress. Clam chowder outstanding. Entree portions large. I had a cranberry stuffed chicken breast. That and the side of spinach and mushrooms were delicious.
