I'm probably not the best authority but ColdStone Creamery and Ben & Jerry's doesn't cut it.
- Mitchell's Ice Cream – San Francisco, near 280
- Sketch Ice Cream – Berkeley, 4th Street
- Ici Ice Cream – Elmwood, Berkeley
- Tango Gelato – Piedmont Ave, Oakland (also in SF on Filmore)
- Joe's Ice cream – Geary St, San Francisco
- Tucker's – Alameda (only 'cuz my friend works there)
There's a Lappert's in Sausalito. That'd be the only chain I'd recommend.
