BOURDAIN ---> LATE NIGHT SUSHI

After a drunken karaoke bout I thought, "Sushi sounds good right now. Why are there no late-night sushi places in Seattle?"

So far I have no been able to find a place that lists its hours past 2am, but here's what I have so far:

Liberty (Cap Hill)
Umi Sake House (Belltown) (1am)
Ohana (Belltown)
Nijo Sushi (Downtown) (11pm most weeknights)
Dragonfish (Downtown)
Imo (Pioneer Square) (karaoke)

I've only tried Umi, Dragonfish and Nijo.
