I work in the area and have tried almost all the places accessible within my lunch break. Sashimi House is more or less what I expected: yet another Chinese run sushi place with nothing special, but you wouldn't mind coming for a meal anyways if you want your standard fare. Good amount of seating. Pretty good service (for a Chinese place).
I had their lunch specials. It's not the best sushi/bento box/whatever out there. It's not cheap or expensive. Everything they do is just standard. Which can be ok. With Sushi places almost as common as finding a Starbucks, this is a restaurant that I would consider only if I happened to be in the area and want sushi (unless you want the crap from a mall food court).
I will probably come again. There's only 1 other sushi place in the area so not a lot of options if I want sushi. And the other place even more expensive.
