Open 24 hours a day, The Fifth Avenue Diner is located at 432 Fifth Avenue (between 8 and 9th Streets) in Park Slope, Brooklyn. This neighborhood favorite diner "hits all the basics" and then some!

From New York Magazine:

This Brooklyn diner’s two adjoining rooms put forth two contrary temperaments. The main space exudes the warm comfort of your typical coffee shop via booths, brick walls, chrome-plated swivel stools at the counter, and nostalgic black-and-white prints of old New York; the larger, second room—accessed through a side doorway—has a definite chill underscored by concrete floors. (Worry not, thirsty reader: At least there’s a bar.) Regardless of the schism, the single menu’s a predictably extensive smorgasbord that hits all the basics (i.e. pancakes, burgers, and roast-beef sandwiches). Low prices add just the right seasoning. Cheap tastes good here. — Aimee Rawlins
