Great downtown location makes this a lunch staple for me.
It's not overly fancy with incredibly exceptional sushi- but the lunch menu features many items (I would say around 15?) all for under eight dollars. This includes an endless supply of green tea, which is par for the course at a Japanese restaurant, but still good, and miso soup and salad. The other reason this gets my stamp of approval? I have been to this place somewhere around twenty five times over the past year, and the quality of food and standard of service doesn't change. I always know what to expect, and it is very good! (Occasionally, service feels a bit rushed, but they can be very busy around lunchtime, so I assume this is a direct result of that.)
For lunch, try the Bento boxes- salmon teriyaki in particular, or the Udon Noodle soup- comes with lots of delicious tempura.
