I worked on the eastside for the better part of 6 years, and the lunchtime buffet at Kanishka is, in my opinion, one of the best in the area. If you get there by 11:30, its easy to get a table and jump right in line. If you get there at noon or later, expect long lines, and probably a wait for a table.
Kanishka has a great variety of veggie and meat options, and I always love loading up on the veggie pakora's and tandoori chicken (on the bone).
I have only been there for dinner once, and they did have a cool special where you can get a meat/veggie "sampler" for about $12 per person. Great way to have a larger variety for a reasonable price.
