I work in the area so I've only tried their lunch and I love it.
They have a great assortment of lunch specials but my favourite is the sushi lunch. You get about 8 sushi pieces with an assortment of sashimi and one maki roll of 8 pieces. This is very filling! All for $13. If you're like me, where you go for lunch specials in the annex for $8... This may be considered expensive, but you get what you pay for so it is worth the spurge.
The restaurant is very small, so you should get there before 12 on a work week or be okay with waiting for a bit. Most people who eat there at lunch also work in the area so they are fairly respectful of their time and don't linger even after their meal is done.
For anyone in a time crunch, as long as you are able to get a seat, the service is quick and the food as well.
