3. Park Avenue Plaza
Huge indoor waterfalls provide a soothing background for those that want to sit or have lunch. On the side there are a few tables where you can study, surf the web or play chess with a friend. Of course, there’s a Starbucks that’s open until 6 p.m. But the best part: a hidden bookstore tucked inside the lobby. Park Avenue Plaza runs all the way through mid-block, so you can enter on both 52nd and 53rd streets.
55 East 52nd Street (Between Park and Madison Avenues) – Take the number 6 train to 51st Street.
