It's right near the vintage Waffle House.
Health Department(!) posted a closing notice on the door & the place is completely empty. I think the Post Weekend section mentioned it closing down in late July due to improper temperatures of food served, among other things (tho luckily no roach infestation!)
I used to go there in a bind if I was hungry for a lot of sushi but didn't want to spend a fortune on just a few pieces. Danbine was run by Soho Deli & they charged $10 for all-you-can-eat (self-serve, so no tip necessary).
As a better alternative, there's the sushi et al buffet at Ben Kay at 15th & H for about the same price (green tea included), with table service & a nicer decor.
