Been going to B & H for over 25 years..
In the city where prohibitive prices could force a person to starve to death, this place is an absolute oasis. The soups, the challah, the tuna sandwich, and the coffee & dessert all hit the spot, and you can satisfy your appetite affordably. The staff is concerned, down to Earth, and pleasant. I am not sure why there are not more places like this in NY. There used to be a lot more dairy restaurants. This is one of the last of a (unfortunately) dying breed. 5 Stars!
If you're in the 'hood, definitely stop in. the mushroom barley soup is amazing. As are the veggie lasagna and the mac & cheese. They guys who work there are super-firendly and you can't get cheaper home-cooked food in manhattan. It's best to go on a cold night with a close friend or a good book. Stay away if you're claustrophobic
