Rudy's Pastry Shop is a little place my boyfriend and I like to go to on Sunday mornings. The place is super small and cozy and full of all the sweetest treats you can find. They have such a large selection of pastries and the coffee is just as delicious. The location is cute as well and a nice place to stroll afterward. There is a cute record store right around the corner.
The best views on Brooklyn and Manhattan. Forget the sweaty and expensive tourist buses, the ferry is just as much as a subway ride and breathtakingly beautiful.
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!
Cobble Hill Cinemas is a cozy little neighborhood theatre. It has all the charm Brooklyn has to offer, screening new releases as well as selected independent films.
