If you're looking for some nice, light summer food, try checking out Fulton Station @ 150 Fulton on the corner of Broadway. They deliver too. 212.227.8383 It's actually in the subway stop arcade. Anyway, pretty yummy bibimbap there. His kim bap sushi roll has also got a nice balance between sweet (egg omelette), crunchy (carrots, cucumbers) and mellow (spinach with sesame oil).
Anyway, I normally wouldn't be inclined to post this review, but as luck would have it, I spoke with the owner and he said that business was pretty so-so. Given the location and the lack of advertising, I can see why. Still though, everytime I've ordered stuff from here, it's always been top-notch. You'll get an authentic, healthy (lots of fresh veggies) Korean meal for cheap. Better yet, you want have to deal with the post lunch coma!!
