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!
Taco Chulo is a great Mexican restaurant that has a good selection of tacos and burritos and of course has interesting blends of margaritas. I probably eat here at least once every other week.
