Ghirardelli Chocolate shops are famous for a reason! Try saying you don't like ice cream when there is melted peanut butter sauce dripping down your cheek.
While the original Ghirardelli shop is in San Francisco, the location in the old Gaslamp District of San Diego is a great place for some California chocolate and ice cream. It is right next to an old movie theater and plenty of hip shops and restaurants. Definitely worth a visit!
