I've been here a couple times for lunch and Sen Sushi doesn't disappoint when it comes to decent AYCE sushi for a good price.
The sushi and sashimi taste fresh and I usually just load up on those alone since the tempura, sushi rolls and some of the kitchen dishes, like the chicken teriyaki, are only okay at best. I can only speak for the lunch menu as I've never been here for dinner, so I'm probably missing out on a lot.
The decor is really nice and service is good.
I would recommend this place if you are looking for a great value AYCE.
