For Peets Coffee and Tea in California, I would stay away from the straight espresso because (in my opinion) their coffee is optimized for drinking with milk.
But there's more. Here's a Peets decoder:
If you want a cappuccino I recommend ordering a small caffelatte.
Yes, you heard that right.
For Peets, small caffelatte = cappuccino.
Their cappuccino is...not a cappucino. More like a gigantic macchiatto: milk foam and espresso, and practically no steamed milk.
That said, the small caffelattes are generally quite good, even excellent.
In San Jose, California, I recommend the Los Gatos Coffee Roasting Company (

The Los Gatos Coffee Roasting Company has good light meals, too. I'm not going to give as hearty a recommendations for the barista-prepared drinks, however. Too much variation there, but I did get a breve cappuccino on Saturday that was quite lovely, served in a real ceramic cup with a spoon (and I didn't have to ask for the spoon!). Perhaps it was the decadence of the cream.
Here's the breve cappuccino:
