There are a couple of Korean food carts near where I work. I guess they’re competitors, though they’ve done a good job of just slightly differentiating their menus. The both have bulgogi and chicken and the like, but whereas the one on L Street also offers bibimbap, the one on K Street instead offers a delightful item that is new to me: kimbap. It’s kind of like a sushi roll, but with cooked meat (or egg) instead of raw fish. Plus pickled vegetables, of course. It’s fantastic!
The resemblance to sushi is not a coincidence; kimbap is apparently derived from the maki sushi concept. The Wikipedia entry for kimbap describes it thusly:
Gimbap or kimbap is a popular Korean fast food made from steamed white rice (bap) and various other ingredients, rolled in gim (sheets of dried seaweed or nori) and served warm in bite-size slices. Gimbap is often eaten during picnics or outdoor events, or as a light lunch, served with danmuji or kimchi. It is similar, but not identical, to norimaki, one of the many variants of the Japanese rice-based dish sushi.
If you’re here in DC, stop by the Korean cart at K Street NW and Vermont Avenue. The kimbap is $4 a pop, and includes a whole big roll sliced into about 8 pieces.

I think I might have to check this out tomorrow. I walk by that cart everyday.
