This is a very delicious Sandwich place in my neighborhood. I normally order the #5 - Bell' americano. It's a great sandwich. Also try the wonderful cookies.
The best way to enjoy Manhattan is from Brooklyn. Transmitter Park offers views without the crowds, and you can pick up coffee-to-go and treats from nearby Ovenly. The India St/Greenpoint Ferry is a 5 minute walk and will take you all the way to the Rockaways in the Summertime.
Roll N Roaster is a fast food place in Sheepshead Bay that has been open since 1971. Get the roast beef sandwich with cheese and a bottle of Moet champagne (not joking).
