Take a walk to High Line, if it is not too cold
Omg, so much to see/do/eat, etc in NYC.
Definitely Chelsea market if near the HighLine.. Los Tacos is fantastic.
Mario Battalli's Eatily for all things Italian.
In the neighborhood, If dining on company expense, avoid Moritimoto or Del Pasto however 11 Madison is fantastic. For breakfast/lunch Grainne Cafe in one of the oldest building in chealsea has fantastic crepes.. I usually order Crepe Maison with chicken/goat cheese and leeks!
Winbar/tapas, Bar Jamon is a must! For Paella, Socarrat.
Underground (no name on door) Mex restauarnt Pulqueria in chinatown is fun. Flex mussels for Mussels.. not sure if they still have all you can eat happy hours anymore (I can eat 3 buckets with frenchfries easy)
Another fun place is Le Relais for French sliced steak and fries... your only option is how do you want your meat cook.
have fun!
Sometimes on sundays certain Broadway shows raffle out matinee tickets. I kinda remembered giving out 20 tickets. Me and gf saw 2 shows this way.
