While this is just a tiny chain-restaurant in the mall, I'm actually quite surprised that there isn't any reviews here. Maybe it's that people thought it didn't deserve a review or maybe it's that everyone's been here.
Whatever the case, Sarku Japan offers great value for what you get. As you walk up to get in line for good eats, there's almost always an employee with some chicken samples for you to try. And you should have a sample because that will determine whether it's worth it or not for you since almost everyone gets the Chicken Teriyaki. For roughly $5 ($7 if you get a drink) you can get some delicious Chicken with rice and vegetables and can even upgrade to double meat for $0.99 extra. It's sizzled right in front of you, and the end result is absolutely delicious. Their chicken egg-rolls are quite good too, so make sure to look for specials where it's included.
The only drawbacks IMO are the fact that it's in the mall and the limited menu. They have other items besides Chicken Teriyaki, but they're generally not ready-to-go and they don't taste as good. If you can get by these problems, then hopefully you'll enjoy Sarku as much as I do.
