Have you tried Suprema Pizza (across form NY Penn Station 31st and 8th)? The slices are a pretty good standard NY Slice, though sauce is slightly sweet.
I like all this mention of pizza. I lived on the UWS from 2006-2012 and have eaten many slices across the city. My Pizza faves currently are Sal and Carmine (UWS), Patsy's Original (East Harlem), Prince St Pizza (LES), Joes (Carmine St.),Best Pizza (BK) Di Fara (BK when Dom makes the pies).
As for CAN JAM, I look forward to checking out some IEMs, notably the Empire Ears Legend X and Noble Khan, while also considering upgrading my cable to a EA Leonidas II.
I had a great time last year and fully expect to walk away from the event with a diminished bank account. Cheers!
I used to go to Supreme pizza for lunch at least once a week when I worked on 34th and 8th.
