This is a 3.5 star review, rounded up to four stars.
My family came here after receiving some coupons in the mail and we were excited to try them. Came here on a Friday night, so we paid the weekend price ($26.99 for adults). Lots of menu items to choose from and I was surprised to see scallops and squid on the sashimi menu (for the weekend)! Not something you usually see at all you can eat restaurants.
They also have a variety of torched sushi. The torched sushi was average, they use the same style and sauce for each one so the variety wasn't as good (unlike Kaka). There was also a lot of rice with the torched sushi, which is to be expected from an AYCE place I guess. I would have preferred slightly smaller pieces. The rest of the sushi and sashimi we ordered was really good and really fresh.
The cooked foods were tasty as well. Their shrimp tempura is very well done, with a light flaky tempura batter. They also have a shrimp skewer that's really good. Senjyu also does drink specials every day, and on Fridays it was $1 off beer, so not a bad deal if you wanted a drink. The day we went, they also had oysters on special so we each got a raw oyster on the half shell. Not bad!
Definitely willing to come back again. The service was quite good for an AYCE place so I enjoyed myself immensely.
