THeres a special pancake house thats really good. Pancake as big as your plate. And there is this Shwarma place in Leidseplein. I really wish I could remember what its called. Its on a side street that runs beside and then behind The Bulldog Coffee shop. Its on the right had side, red sign that says Schwarma. Best damn sandwhich in all of amsterdam I promise. Just get a Schwarma, some fresh fries and a coke and youll be in heaven. I was just there in March.
Sorry for the block of text, ENJOY! Oh and do a bike ride. Mike's Bike Ride's is pretty good. Might as well do it day 1, itll help you get familiar with the town and layout. Peace.
