Anyone who has ever spent a lost weekend in Amsterdam is sure to have suffered the munchies at some point during their stay. On such occasions what you probably need is a good fast food Google Maps mashup. Step forward SnelleHapMap.
SnelleHapMap is a map that shows fast food restaurants in the Netherlands clustered by province and zip code. The map shows the locations of Domino's, Subway, Burger King, FEBO, McDonald's, New York Pizza and Kentucky Fried Chicken restaurants.
It is possible to select any combination of the above restaurants on the map at any one time. Clicking on a map marker will open an information window with the address of the restaurant.
There is even a mobile version of the map!
