Honestly, if you are only going to be there for a day, focus on Time Square. There is plenty of stuff there from the huge Toy s R Us, to the flashing lights and the shopping.I m sure you will be by radio city music hall. Be sure to see the tree at Rockefeller center, and the ice skating rink!I wouldn t eat around there though, if you can avoid it. It s mostly just standard American fare (burgers, burgers, more burgers), and instead go over to 8th ave. There is a lovely little hole int he wall on the corner of 38 and 8 (which is still near Times Square) called Gogo Curry. It s Japanese style curry. Not too spicy! It s delicious, trust me! There are some other good little chains like Grey s papaya, if you like Hot dogs.Hope that helps!
For a day trip- I would focus on Times Square or 5th Avenue. Times Square is very crowded but has many great features. The lights and the atmosphere is awesome. They have the huge American Eagle store, Toys R Us, Hersheys, M M, and other smaller shops. All the theatres are in that area. You could go to 5th Ave where they have the NBA store, the Disney store, Abercrombie, American Girl, and FAO Schwartz. You are closer to Central Park which is really nice. A few months ago I went to see the Little Mermaid with family and friends and this is what we did. We got off the train at Penn Station and took a cab to Central Park. We walked around a little and then started walking down 5th Ave. We hit FAO Schwartz first which is right on the corner of 5th Ave and 58th Street. 2 more blocks down is the Disney store which has 3 floors full of Disney goodness! Most of the things they sell are things you can only buy in Disney World/Land. Across from the Disney store is Abercrombie and the Gap. They have Loubiton and Tiffanys one block down. You can see the Trump Towers which is amazing. I adivse you just go in and use their bathroom because the inside is all gold. Its breath-taking! One more block down is the NBA store and then St. Patricks Cathedral. And if you go down one more block its the American Girl Store and H M. Then we cut down 49 street to 6th ave (avenue of the americas) and saw radio city music hall and went ice skating at rockefeller plaza. After that we went up 49th street to Times Square which is one block up. We ate at Planet Hollywood but I wouldn t advise you to go there. The food is terrible, as well as service and very pricey! But after our show we went to the M M store and the Toys R Us. And took lots of pictures of the signs and lights all over.Have a great time!! =)
