I also love my local Japanese Sushi & Seafood Buffet in Roseville CA: Mizu All the sushi & sashimi you can eat for only $8.99 (lunch). Its nearly as good as the expensive Sushi Bars, at a fraction of the cost! "Mizu" is very similar to the chain called "Todai" -- except the food & service is way better, at a more reasonable price.
My favorite restaurant is "Bawarchi" which i always use to go with my family for atleast four times in a month!
