Aijsen Noodle "AKA the Noodle Girl" is a chain that has been very popular in Asia. They have one location in Chinatown next to Chinatown Fair.
It's a great place to get some fast Japanese food for a reasonable price. I recommend their grilled crab yakatori and chicken teryiaki ramen. I find their broth for their noodles particularly tasty!
They also have sushi available! YUM!
