This wide canyon of corporate media towers is imposing as much as it is expansive. The lineup of repetitious buildings and street lamps create for a dizzying optical illusion befitting M.C. Escher. Sitting right between Times Square, 5th Avenue, Rockefeller Center (and to a lesser extent, Grand Central), this stretch of 6th Avenue always has plenty of tourists bustling through.
In my post on 50th St Between 6th Ave and 5th Avenue, I didn't say much about what is potentially the most noteworthy landmark on the block: Radio City Music Hall. I could argue that it was because I had so much else to write about on that block. I could also claim that the real "front" of Radio City resides on 6th Avenue, and didn't warrant mentioning on a side street. Pick whichever suits you best.
Opened in the 1930's during the height of The Great Depression, Radio City is so iconic as to almost be a caricature of what many people imagine to be Art Deco. The beautiful theater inside is nothing short of breathtaking. If ever given the opportunity, do not pass it up. It's a bit off-putting to see them using LCD TVs on the front and side of the theater to advertise upcoming performances- somehow it undermines the classic marquee above.
