Someone told me that Humphry Slocombe Ice Cream in San Francisco is very good but never tried it..even one in the Ferry Building.. Looks like it might be turning into another Haagen-Dazs or McConnel's which is based in Santa Barbara - very rich but over-hyped. Grew up on Breyer's, then Dreyer's and Swensen's in the bay area - Fenton's in Piedmont/Oakland was good too. Nothing like really good gelato though!
Everybody has their ice cream favorites:
