For lovers of good Czech food I want to recommend very good Czech restaurant in Bay Area. DJs Café in Concord. Being a Czech I tried all Czech restaurant in Bay Area and I like this one most (the rest of them are just so so). The place is in the mini mall where you would expect 7-11. The food is very good and not so expansive. I personally like Wiener Schnitzel which comes with home made potato salad. They also make very good Svickova (sour brotten) and goulash soup. And yes they do serve original Czech Budweiser (they call it Czechvar in USA).
One more thing, I found very good market selling central European stuff (sausages etc). It is on Geary and 20th Ave, in San Francisco it is called New World Market.
