Sushi Wagon is my new favorite lunch spot. It's very small, but that gives it a sort of NYC vibe. The service is great. So far, I've only had the Salmon Teriyaki combo (filet of salmon w/sauce, 4 california rolls, salad with a citrusy dressing, steamed rice & miso soup - $7.50), but the other dishes I've seen served looked very appetizing.
Pros: Inexpensive, Friendly service, Fast
