Hey, I just went to Corvallis to visit a friend yesterday, and she introduced me to an awesome Japanese restaurant that I thought people might be interested in.
It's called Aomatsu. They just remodelled, and the new restaurant is really cool! They have a section where one of those grills is set in the middle of each table where you can watch the cooks prepare your food to order right before you, AND they have a sushi bar, AND a section with traditional-style tables: the short ones on a raised platform where you kneel while you eat.
What's better, the food is great, and there's a lot of selection! Plus it's reasonably priced. To give you an idea, I and my friend had four rolls of sushi (8 pieces per roll), a glass of iced tea, and two bowls of rice, all which came to a combined amount of about $23.50.
In addition to sushi, they have tempura, and a wide variety of other Japanese foods. The sushi we had was really good, and I quite expect the rest of the menu to be the same.
Next time I may try their don katsu...
We in Eugene/Springfield sometimes used to go all the way up to Beaverton to get to a good sushi restaurant, but Corvallis is about half the distance, and it would be a great substitute. I've been thinking of taking a gang up there sometime for lunch or dinner. Perhaps we could even stop on the way to or from Portland sometime. If anybody would like to do that, speak up!
