Don't let the worn exterior fool you, Yoshi's is a safe option for Asian fast food. There's a reason it's been around for as long as I can remember!
It's got a limited menu of terriyaki bowls and the like (meat + vegetabes + rice), spring rolls, and even some sushi, which I have not tried.
When I'm in a hurry, it's all about grabbing the terriyaki chicken bowl. About 6 bucks and 6 minutes later, I've got a satisfying lunch!
I mean, don't expect anything fancy. It's just OK. But it's worth the break from the burgers and burritos on just about every corner around. =)
