As the nicer of the two Ah-Sos in Arrowhead, I dig this one better. It's newer, larger and more stylish.
This place rakes the people in for lunch time, and you have the option to sit teppenyaki style (around a huge grill) or at a table. We always opt for teppenyaki. Never much of a wait for lunch, but I understand dinner can be hectic in this corner of the Valley known for Applebees and Chilis.
The food here is fresh, flavorful and always done up with a typical entertainer-like cleaver chop show - and service by these guys is usually stoic and efficient. This time I ordered the grilled shrimp and chicken done up with fried rice and veggies - and it was delicious. I tend to stay away from the sushi although they do have it here - so can't speak to that.
I come here infrequently, as lunch can set you back $15 - $20 or so. But make no mistake - it's worth it.
