You're giving direction to someone to find a foodtruck in NY city.
When you get out of the Museum Of Modern Art on Fifth Avenue, go right. Before St Patrick cathedral, turn right. Go past Rockefeller Centre and turn right on Seventh Avenue. The food truck is on the corner of Seventh Avenue and 57th street.
In US spelling, we write 'Center' instead of 'Centre', the pronunciation is the same, though.
In long form,'the Cathedral of Saint Patrick', therefore, 'Saint Patrick's Cathedral' (showing possession).
