I like Foosia. It's fast. It's casual. It's reasonably priced. It's tasty. And it currently has a Yelp offer for a free beverage. What more could you wish for when you're in search of a quick bite?
You select your base (rice lettuce, noodles), your protein (tofu if you're vegetarian), and your sauce (samples gladly given). Not up to the standards of a fine Chinese/Asian restaurant of course, but equivalent to the relationship that Chipotle has with good Mexican food.
Overall, a nice "healthyish" alternative to fast food.
