This is a great park, from free concerts to summer to the Brooklyn flea markets over the weekend or take the ferry across the river. Rain or shine I never get sick of that view.
To have the best lunches like a 'fried peanut butter sandwich', lounge or book a room for a few days in the heart of the city, visit 'The Ace Hotel'. Ease down in the couches, order a Brooklyn Beer and relax. A great place to meet up.
