The eastward extension of 8th St./Astor Place past 3rd Ave. There are many bars, restaurants, and shops (many with a street vending presence) on the block between 2nd and 3rd Aves. There's always quite a mixture of folk walking up and down the street and within the area not to mention the slew of students from Cooper Union and NYU, which has plenty of dormitories and facilities nearby. Be warned that it can be unpleasantly crowded with slow-moving tipsy people at times, but it is a good place for people-watching.
