"No hot dogs here," the guy manning the cart said. "I sell wurst, not hot dogs." And that he does. Bratwurst, Knockwurst, Alpenwurst, Currywurst, Hungarian Kielbasa and a few others. You get them whole on a bun, or cut into slices

Not only wurst, it's pretty much a full German restaurant. Red Cabbage. Sauerkraut. Potato Pancakes. Lentil Soup. And one or two other daily specials.

There's always a line, no matter what time. But worth the wait. There are a couple of Hallo Berlin restaurants too.
