Photo by myself around 7th Avenue and 55th Street, in Midtown.
Looking down Seventh Avenue from the back seat of a cab, you can see the taller buildings near Times Square.
If you're ever visiting New York, I recommend getting in a taxi on a nice day and sailing up or down one of the busier avenues. You get a view that is wholly different from the typical pedestrian view. Another alternative is to get on one of the many city buses. The fare is the same as a subway ride ($2.25 per ride).
Because you move faster than on foot, you're not hung up so much on the little details, and see the sweeping view of the street.
Traffic on Seventh Avenue runs north to south, however, so if you're in a vehicle, the only way is down.
