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. 

ANTHOM’s gallery-like store on Mercer Street is all about presentation, and their selection of pieces from designers like Lady Artigas, Mari Giudicelli, Yune Ho, Marni, and Suzanne Rae is displayed with an eye for design.

I discovered the Frick my first week in New York, during a heat wave in August. The galleries were surprisingly empty, with only the occasional visitor strolling through the rooms, gently creaking the floorboards. I stood for a while in front of the Bronzino, a portrait of a boy standing against a background of green drapery, and then sat in the courtyard for a long, cool hour.

Leaf through over 30,000 artists' sketchbooks in what may be the world's largest collection.

This is a pro tip, but also a summer tip, take the ferry from Lower Manhattan to Rockaway and spent the day. The beach is great and the area is impossible to gasp that it's 30 min from Manhattan (without traffic) - Eat as many tacos you can, cause it's the best in the state of New York!
