Some good Kolache shops:
West - Slocacek's, Czech Stop
La Grange - Weikels (also in Brenham), there was also a good one called Das Kraut Haus that I don't believe is there anymore.
Arlington - Kenner's Kolache Bakery
On a related note: I've noticed that some Texas Czechs/Bohemians don't regard "Kolaches" with sausages in them to be real Kolaches--only the jelly, cheese and/or poppy seed kind are the genuine article. To the purists, sausage "Kolaches" are technically just "sausage rolls" or "pigs in a blanket", though just about all Kolache shops in Texas serve them along with the jelly/cheese/poppy seed type.
