If you go to China town or little Italy it's a lot to choose from. It's only few rides away from Brooklyn via Subway
There are a lot of street food sellers around Brooklyn bridge within a walking distance. I tried Grimmaldi's pizza so delicious and for desert i went to Brooklyn ice cream factory. Remember to carry cash with you because most street food sellers don't except credit cards.
Lots... Just walk around the area, there is a variety of food to eat.
