Visiting NYC Next Week (Jan 15-20)

Hi everyone,

I am visiting NYC with my wife for about 5 days next week from San Diego, CA. We are staying near MSG and are looking to mostly walk/subway around town. In an effort to maximize our stay, I have a few questions:

• Is it better to buy a week pass for the subway or pay as we need to use it?
• What are some attractions that most tourists dont know about when visiting?
• What are some restaurants that are must try? ($15-$30 / entree)
• Are observation decks worth the $40 entry fee?
• + any other tips/tricks you can offer would be greatly appreciated.

Looking forward to visiting your great city.

Thanks in advance for any insights!

Edit: Thank you guys for all the helpful tips and info!!
