I gave up on S'berger a long time ago. They've always been no more than an average chocolateier, IMO, and since they were taken over by Hershey's, well, there's just no reason to give them my $$ any more.
AS for olive oil, there are so many places in CA making good, fruity green olive oil it would be hard to know just which one you're referemcing.
Not Pt. Reyes, Pt Reyes Station. two very different places, but each with it's own charm and interests.
For a real cheese treat, you've got to check out the Cheese Board in Berkeley, across the street from Chez Panise. Probably the best, most fully stocked cheese shop in the area, although there are some places, like the Pasta Shop, that may have some more interesting cheeses at times.
The thing about the Gourmet Ghetto is that there's little or no need to ever go into a regular supermarket. You can shop in specialty shops all day long. Apart for some staples, like milk or ketchup, I rarely shop at typical supermarkets, unless you include Whole Foods as a typical supermarket. And even there I limit my purchases to just a few items.
Come to Berkeley, bring your shopping basket, and we'll cruise the Ghetto ... La Farine for brioch and their wonderful rustic loaf, Acme Baking, Semifreddi, and the Cheese Board for wonderful, fresh from the oven sourdogh baguettes, AG Ferrari for some amazing Italian products, including some of the most amazingly delicious DOP San Marzano tomatoes, Berkeley Bowl and Monterey Market for produce, Magnani Poultry - you want birds, they got birds! - a couple of Halal markets, Tokyo Fish market for your sashimi grade fish ... and so much more. It's paradise for foodies.
