I love walking through Grand Central...you'll feel like you're in a 1940's movie. The halls are great for shopping and while most are stores you've seen elsewhere, there are a few more unique shopping options. The food hall is great just to see the variety of stuff and the lower level offers little food stands from local favorites. When I was there in December, there was a crafts market also going on in one of the halls and had local artisans selling high quality gifts just in time for Christmas.
