This isn't my favorite cuisine so I can't say that I've tried many of the Czech (or Czech-ish) places in the area, but I have been to Korzo on 5th Ave in Bklyn a number of times to drink or to eat or to attend one of their live jazz concerts & I've liked it. It's a laid back place with an unassuming, non-pretentious vibe. You might want to try it.
