Mitsuwa marketplace in costa mesa. Not much over $5 for a quick lunch. + I then buy the rest of the day's + the next day's meals for 'round $5 each. Good eats, way better than fast food, and tastes more natural/home cooked (duno how to word it) to me.
My old favorite nice time deli, Irvine branch (in english. Hao Nian Dong in Mandarin) has been weird for the consistency of the food since remodeling... I've been going there alot less. If they can get back up to par, I'd probably return as a regular. [also known as good time cafe-depending on location. owners all related by blood/marriage]
