Although I live very close to this place, I don't usually jump at the opportunity to visit United Bakers, something about an all dairy diner (that does not meet Kosher requirements) doesn't appeal to me.
However, they have not been in business for 100+ years for nothing. What they do, they do well, and locals know that. They have a warm and inviting atmosphere with low lighting. A varied menu which makes you not (usually) miss the meat and generally when I end up here I enjoy what I've ordered.
Their soups, baked goods, and eggs are probably my favourite items on the menu.
However, I should mention that despite an aging clientele, they are not accessible. They will do what needs to be done to get someone in a wheelchair inside but it's not always easy.
It's worth a visit if you have never been and all I can say is that I hope they remain in business for another 100+ years!
