Andres, the Hungarian bakery and cafe on the Upper East Side, and ask for a babka, they'll hand you this bundt cake-looking thing. "The Hungarian version of babka," they explain, but its real name is actually Kugelhupf (or Gugelhupf or bábovka, depending on what part of the world you're in). Best version in NYC, but only sold whole and he only makes 6 a day.
