I have been to Maria Bonita a few times for lunch. We normally go just before noon and so far haven't had much of a wait. The chips are crispy, warm and fresh. I think the salsa is good - it tastes freshly made and has good flavor.
They have a good selection of lunch specials which are a good value. In my opinion, the quality of food here is very good. The bright decor and open feel of the space makes it warm and welcoming.
