Hidden in a corner away from traffic and walking paths is Yoko's, a small family-owned restaurant not open past 5:30 pm. And yet the food is wonderful: it's very much home styled with delightful touches that people who are used to Japanese fast food (Taki's, Tokyo Joe's, Kokoro) would not expect. The staff may not speak perfect English, but they are friendly if slightly reserved and the food comes quickly. It's hot, it's delicious. You can see into the kitchen from the main dining area, so you may learn a few things about how your food is prepared.
Pros: Free parking w/stamp
Cons: Not open late evenings
