There have been only two moments in the decades I have lived in the Bay Area that I saw a Polish food and actually got lightheaded. The schock of seeing it. The pleasure.
That's what happened Saturday when I saw the big baskets of Polish hard rolls at Delikateski in Concored.
Not bagged in plastic which softens the crust. They were almost like the kind you find at many East Coast Polish bakeries (the interior was slightly denser). Huge bushel baskets of them. Maybe they are the same as Kaiser rolls, but I've never seen those in this area either except bagged in plastic.
If you are not of Polish ancestry or a fan of this type of roll, it's not worth a special trip. This is no Acme. For me, personally it is worth a special trip. This will not turn you on to Polish food if you are unfamiliar with the cuisine.
Can't give you many details. I won't bore you with the long story, but I annoyed the store clerk by asking for a bag for the rolls. All was well in the end she was feeding me samples of cold cuts. However I knew asking questions like what bakery they were from and what days they were available would not be a good thing.
Speaking of cold cuts, they have a huge selection. I had this excellent Eastern European Prosciutto. It is a raw pork loin that is smoked, said the store clerk. I didn't catch the actual name so I asked to have it written down so I could buy some next time. The clerk shot me a look and wrote down "smoked pork loin" in English. You might understand my not asking more about the rolls.
Huge Eastern European beer selection with questionable Eastern European wines. Big dairy selection. They had Amish butter which I haven't seen before in this area.
Not sure if sampling the cold cuts is standard or the store clerk was trying to be nice after the initial incident.
I really can't tell you if the cold cut selection is better than the Russian market on Clement in SF. I just don't like the place on Clement. It has a horrid deli and despite the selection in the groceries, deli, etc. I never find anything that interests me.

Goggling for the address, this earlier Chowhound post appeared. As it mentions there is a big selection of Eastern European bread, but with few excepetions, nothing you can't find elsewhere ... Bavarian Breads for example. There WAS an unmarked rye that I haven't seen before.
