The atmosphere is a bit dated or ktchy depending on your pov. The food is what you would expect from a diner - some great items like meat loaf or mac and cheese and some so so items with interesting names. The hours are a bit weird so make sure you check times before venturing down 9th.
It is the staff that really shine. We go for Sunday lunch with grand kids about 6 times a year and Mardy (the server) remembers them by name and what they had the last time we were there. It is hard to find such a family friendly venue that treats kids like an important part of the table.
