Went with their Bibimbap dish ($13) which was served in a piping hot stone bowl. The presentation of the plate was excellent, very colourful and appealing. As a side-dish I was also given soup since the Bibimbap is quite a dry fish and the occasional sip of the soup allows you to keep going.
The plate was full-flavoured and quite enjoyable. I don't have extensive experience with Korean cuisine but I definitely want to after this meal.
Service was fast and polite. Soup refill without even asking! Waitress didn't speak much, if at all, not sure if this is how service is done so... I'll go with traditional Asian experience. :)
Negasake has a nice dining setting without being overbearing on the Asian theme. Pretty fake tree? Very quiet, no other patrons so I'm unsure if location is bad or I came in at the wrong time. Or perhaps there's much better elsewhere?
Either way, I liked it and I want to experience more Korean cuisine!
