While you're waiting for Chatham's to reopen (so you can confirm it's number 2), head over to the real Best Chocolate in the Valley, the Bernard Callebaut store near Frank Lloyd Wright and the 101. They don't have 270 kinds, just the best chocolate.
BEST CHOCOLATE - 2007
Chatham's Fine Chocolates - CLOSED
Chocoholics, take note: The shop just moved from Scottsdale to Phoenix, where it reopens in early October.
