While the current trend in noodles may well be ramen, this bafflingly-named Japanese restaurant just ten minutes from my apartment specialises in udon. Unless you are my friend Diego Zambrano it will probably take you several visits to get through all the things you need to try on the menu - the gyoza are otherworldly, the sushi 'tacos' clever enough without being silly. New York has thousands of awful Japanese places; this is not one of them. It's super nice to come in on a Sunday night and eat at the bar next to curmudgeonly old guys barking at each other in Japanese.
Part of the Marlow restaurant group, Diner is one of the more casual / rustic options. The menu changes daily and is written out (most likely upside down by the wait staff) on your table or the back of a receipt. The only constant item is the burger, which to be honest, is one of the best in the neighborhood. If they have a breakfast sandwich for brunch, get that. The fried chicken sandwich (with dark meat) is also a favorite. They make scrambled egg dishes better than most. Dinner is solid all around (they crush a steak for two). Homemade ketchup and dijon mustard are on every table, so regardless of what you get, these two condiments are worth the visit.
Recommended by my friend and talented illustrator, Isabel Castillo Guijarro, this spot makes incredible cappuccinos and is in one of my favorite NYC buildings, the WoolWorth Building
