New York $1300 a month

So I am trying to keep all of my NYC expenses to be under $1300 a month. So here is the breakdown...$800 for rent, $120 total bus fare (Megabus-$1-$22 one way from MD to NY), $80 unlimited ride for the Subway, and $300 for food and drinks. So how does a 43 year old male make it on $300 for food and drinks in NYC. I eat a monster bowl of oatmeal for breakfast, a can of beans or cup of brown rice for late afternoon lunch, drink mostly water and look for networking groups that offer free hors d'oeuvres and wine for dinner! Throw in a piece of fruit and you get a $1,300 a month. Priceless!
