I have to give props to one of my alltime favorite restaurants. It's a Greek place on W. 113th Street (between B'way and Amsterdam) called "Symposium". Fantastic food and sangria and lots of it and, best of all, cheap!!! (I don't think it's been discovered by tourists yet, so don't tell anyone

)
I'm trying to remember how you'd get there from where you're staying. The M104 bus or the subway redline to 110th Street.
No matter where you end up going, enjoy your time in NY!
