Do a search using the home screen "internet search" applet; eg: Pizza (zip code). Google will return it's normal search results page. At the top of that page hit the "maps" link.

If you installed sashabe's .mozilla/microb/chrome/userContent.csss code correctly, a full screen map should open with push pins at the locations for pizza in the searched area.
Tap on the one you like and a balloon will pop up with that locations info and links.
