In March 2009, I spent four days in NYC experiencing art, culture, science, long walks, cars, noise, prohibition signs, low fat products, American huge watery coffee (just looking at it...), M & M store with artificial chocolate scent, everyone consuming cups with all sorts of beverages (unfortunately including me) , foreign English accents, water towers, city, village, shopping, Broadway, east village, queens, fast food, and macrobiotic food.
After a despaired day of finding only fast food restaurants, there were quite a few nice restaurants in the University and East village area. Pizzeria Arthuro: Life Jazz and Pizza, just to name one.
I can definitely recommended for Montrealers, who enjoy hanging out in the neighbourhood Plateau, to go see Williamsburg/Brooklyn with its cafes and arts spaces. El Beit Cafe, on158 Bedford Ave, Brooklyn, is recommended. I felt like in the Plateau being actually in NYC.
