Visiting New York City never gets old. Even on business with very limited time you can always enjoy the Big Apple. Recently I have been staying at the Courtyard Marriott next to Madison Square garden. For me this is the find of the year. Awesome service. Convenient location and very reasonably priced. Plus, there is always something happening at Madison Square Garden with the various sports teams and concerts. Check the schedule in advance.
For meals Hakkasan on W 43rd St is my go to restaurant if I was in town for one night. Any of the Wolfgangs restaurants dotted around the city remain my personal favorites for steak and if you are looking for another steakhouse alternative close to MSG then Nick and Stefs is an excellent choice. Another new favorite of mine is Nomad on Broadway; excellent cocktails and the food is small plate and delicious.
Within an hour you can take a tour and visit the various hotspots; Rockerfeller City, Time Square, One World Trade Center, and The Empire State Building to name a few. So even with limited time you can see a lot.
Hope you get to enjoy New York City,
