This is a great place in the financial district for a "nice lunch" without breaking the bank. They serve up japanese and korean food so you can get a sushi/sashimi combo, a bento box, bimbimbap, etc.
Service is decent and relatively fast so you can be in and out within an hour. Reservations are recommended, especially in December when lots of people splurge for the holidays and get together with friend/coworkers when things aren't quite so busy at the office.
I come here every time I have a craving for hwe dup bop (Akco's version is rice topped with arugula/field greens, and sashimi with korean spicy sauce). This seems to be the only place in the downtown core where you can find it (or at least so I could find).
It's a pretty solid choice for when food court sushi won't cut it, but you don't want to spend the $$$$ to go to a place like Ki.
